What on earth is a palletizer? All I know is that it’s packaging equipment.
The palletizer is to put the cartons that have been packed into the container on the pallet (wood) according to a certain arrangement code, which can be stacked automatically, which can be stacked in multiple layers, and then pushed out to facilitate forklift transportation to the warehouse for storage. This equipment adopts PLC+ touch screen control to realize intelligent operation and management, which is simple and easy to master. The labor force and labor intensity can be greatly reduced. The design adopts the concept of high speed, stability and space saving. The use of separate plate, faster, more space-saving. One machine is multi-purpose and can be adjusted quickly, so you don’t have to worry about changing stacked products.
Transportation method of pear
Transportation method of pear
1. Pay attention to anti-vibration treatment, light loading and light unloading, reduce abrasions between fruits, in order to avoid mechanical injury.
2. Attention should be paid to fruit temperature, humidity and gas environment during transportation, timely exhaust and moisturizing, etc. When the external temperature is higher than 10 ℃ or lower than-1 ℃, it is necessary to adopt thermal insulation measures such as refrigerated cars and thermal insulation containers. When the early and middle ripening varieties were transported from the north to the south, the transportation time should be 3-5 days, and the transportation temperature should not exceed 10 ℃. When the transportation time was more than 5 days, the transportation temperature would be the same as the storage temperature.
3. Attention should be paid to the safe and stable palletizing of fruit boxes, quick loading and unloading, and good air circulation in the transport vehicle.
Preservation skills
1. Keep the pears in the refrigerator or in the cold room: keep the pears in the refrigerator. The most suitable temperature is-1 to 1 degrees Celsius, and the maximum temperature is no more than 5 degrees Celsius. You should pay attention to the preservation time of no more than 5 days. Do not wash before putting it in the refrigerator. Many people put the pear in the refrigerator and find that the pear has gone bad, which is mostly due to the inappropriate temperature, so we should pay attention to adjust the appropriate temperature.
2. Newspaper preservation: in winter, pears can be wrapped in 2-3 layers of newspaper or soft paper and stored in a cool and ventilated place. if the weather turns warm, it can be stored in the refrigerator for two weeks.
3. Plastic bag preservation: first wipe off the moisture on the pear surface, then seal the pear with plastic film, and finally put it in a plastic bag and store it in a cool place, or keep it in cold storage. This method can be preserved for a week or so.

Storage and fresh-keeping of honey pear
Common and simple storage and fresh-keeping methods
First, storage pre-cooling
No matter what kind of storage method is used, the pear fruit still has a large amount of field heat after harvest, coupled with exuberant breathing, which gives off a lot of heat, so it must be pre-cooled before formal storage. After the fruit is stored in the room temperature ventilation store, it should be moved to a cool place immediately after the fruit is under the tree. After simple grading, it is packed in a fruit box, palletized in a shady place, naturally ventilated and sweated for 24 hours, and then packed or treated with a single fruit. Then store it in the warehouse. The fruits stored in cold storage were also graded in the shade after falling the tree. After natural sweating, the fruits were sent to 10 ℃ ~ 15 ℃ cold storage, then slowly precooled, and finally stabilized at the temperature of 1 ℃ ~ 3 ℃ for long-term storage. This treatment can significantly reduce the respiration of the fruit, remove the heat in the field, reduce the fruit temperature and improve the storage effect.
Second, several commonly used storage methods
(1) the general ventilation storage method makes full use of natural conditions and is a simple, energy-saving and convenient storage method. The storage method is as follows: first, a simple storeroom with the same storage capacity as the fruit to be stored, clean it, then ignite it according to the dosage of 25 grams of sulfur per cubic meter, fumigate and disinfect it, seal it for 48 hours, open the storage door, and store the fruit in the warehouse. The floor of the warehouse should be covered with wooden strips or bricks to facilitate ventilation. The fruit box is stacked on corrugated bars or bricks, 10 kg carton, up to four layers of palletizing. The vents at both ends of the fruit box should face outward, and there should be a certain gap between the stack and the stack, so that the natural wind energy can circulate in the reservoir. In the south, when the temperature is high, the library door should be closed around noon during the day and open for ventilation at night. A dry-humidity meter should be installed in the library to observe the air humidity in the library at any time. When it is too dry, it is necessary to spray some water on the floor of the warehouse, or use humidifying machinery to increase relative humidity to reduce water loss caused by fruit transpiration.
(2) Cold storage is the most effective method for the storage of precocious pears. Its storage effect is the best, but the cost is high. With the internationalization of the market, it is an inevitable trend to carry out refrigeration. The automatic temperature control cold storage can be built on the ground or refitted from the underground storage. A corrugated bar is installed at the bottom of the cold storage to prevent the fruit box from being put directly on the bottom of the warehouse without ventilation. A refrigerator should be installed at the top. Refrigeration machinery must be installed by professionals. At one end of the cold storage, a ventilation port should be installed to discharge the gas produced by the fruit out of the storage in time. In some warehouses, activated carbon or quicklime are placed to absorb the smell produced by refrigerants, and the effect is better. According to the calculation of a cold storage with a storage capacity of 32 cubic meters, the whole cost is 30, 000-40, 000 yuan, the daily operating cost is about 40 yuan, the fresh fruit can be stored for 5000-10, 000 kg, the storage period is more than 2 months, and the freshness of the stored pear fruit is 95%.
(3) hoard in some places, when storing a small amount of fruit, dig a hole in the cellar, cover the bottom of the cellar with plastic sheeting, and put the fruit directly on the plastic sheeting. The effect of short-term storage is better. Some dig a soil cellar at the back of the mountain for storage, which also has a certain effect. However, cellar is only suitable for the storage of small batches of fruits, but not for large quantities of fruits.
What problems should be paid attention to in packing? How to carry out graded packaging?
The main results are as follows: (1) the precooled sweet cherry fruit has a large amount of field heat after harvest, if it is not precooled in time, the covering heat will lead to the increase of rotten fruit rate, and whether the precooling directly affects the storage life and shelf life of sweet cherry. Pre-cooling is to cool the fruit in a relatively low temperature environment after harvest, the purpose is to quickly remove the heat in the field to reduce the product temperature, reduce the load of the cold storage after storage, and maintain the best quality of the product after storage.
The precooling method of sweet cherry is mainly cold storage precooling, the cold storage precooling method is to quickly put the harvested fruit in the precooling room where the storage temperature has dropped to-1 ℃, according to the variety, grade and time, there should be a certain gap between the box and the box, so as to achieve the uniform precooling temperature of cherry fruit. When the product temperature of the cherry fruit dropped to 0 ±0.5 ℃, the cherry fruit was thoroughly cold, and then the precooled cherry fruit was stored in a cold storage with a storage temperature of 0 ±0.5 ℃ or used for transportation. Another method of cherry precooling is cold water precooling, which takes away the field heat of the fruit by water to achieve the purpose of precooling. (2) after harvesting, graded sweet cherries are finally sold as commodities, and the fruits must be strictly graded, such as diseased fruit, rotten fruit, mechanically damaged fruit and bird pecking fruit, and then strictly classified. At present, the classification method is mainly manual classification, strictly speaking, classification and packaging must be carried out in the cold storage, so that it can play the role of pre-cooling in advance. according to the standard of classification, cherries are divided into special fruit, first-class fruit and second-class fruit according to color, size, maturity and so on. The cherry fruits with the same color, size and maturity are divided into the same grade, those with good color, large fruit and high maturity can be classified as super fruit, and those with slightly worse fruit can be classified as secondary fruit, so that the cherry fruit can be sorted out by analogy. There is another classification method is mechanical classification, mechanical classification is only to separate the size of the fruit, the rest still need manual operation to complete the classification work, at present, mechanical classification is widely used abroad.
At present, these two classification methods are mostly visual in the judgment of color, size and maturity. in order to ensure the strictness of classification, the soluble solids, sugar content and hardness of fruits can also be reflected digitally to form a unified classification standard. (3) packaged sweet cherry is sold as a commodity, and its packaging is particularly important, which not only affects people’s sensory effect, but also directly affects the economic benefits. The function of its packaging is to facilitate fresh-keeping, facilitate transportation and promote sales.
The main purpose of the inner packaging is to keep the moisture, quality and taste of the fruit well within a certain period of time. Sweet cherries are not suitable for independent packaging one by one, mainly in bulk. At present, sweet cherries are packaged according to their uses. Sweet cherries used for local fresh food are usually packed with toilet paper, and the selected and graded sweet cherries are packed into boxes according to different levels, and pay attention to filling the box with space to gently shake to tamp the fruits, so that the fruits are not easily shaken and damaged by collision and friction in the process of transportation. after loading, cover the top with a layer of toilet paper, and then seal the box. Other paper is also used in production, as long as the paper is soft. If it is used for the storage of sweet cherries, the plastic film fresh-keeping bags are most used in production, and the inner packaging should not be too large. Choose 0.03mm PVC fresh bags with good fresh-keeping effect for small packaging, generally, each bag contains about 1kg of fruit, and after packaging, put it into a plastic turnover box and stack it on the shelves prepared in advance in the cold storage or cold storage. If it is a long-distance transport fresh-keeping bag packaging can be slightly larger, depending on the size of the outer packing box.
Outer packaging mainly refers to the high-quality packaging that can improve the value, which requires exquisite, small and easy to carry. The outer packaging is required to achieve the role of anti-extrusion, the outer packaging of sweet cherries should not be too large, generally 2 to 5 kilograms is more suitable, choose cardboard boxes with plastic film and printed with signs, it is better to have hand straps, if it is convenient for transportation, but also further repackaging, can be several small cases as a whole, outside the lattice wooden case packaging to be fixed.
In addition, when sweet cherries just appeared on the market, in order to meet the needs of consumers, we can choose a small, translucent, fresh-keeping polyethylene material small packaging, this kind of packaging is more common in the supermarket, generally about 250 grams. Put the cherry fruit into a small tray made of polyethylene material, close to the cherry fruit one by one, and then cover it with a layer of plastic plastic film to sell.
