How to store a large number of carrots in cold storage 100 tons to 200 tons Thank you

Ask the engineer of Shanghai Xiangning Refrigeration. They are professional.

Radish storage temperature 1-3 degrees.

The time that cold storage can store fresh vegetables depends on the variety of vegetables, the short one is one or two weeks, and the long one can be stored for several months. Modified atmosphere cold storage has a longer preservation time than ordinary fresh-keeping cold storage, the fresh-keeping effect is better, and the shelf life after leaving the warehouse is also longer. I am installing cold storage, you can contact me if you need to do cold storage, or search for Guangzhou Glacier Refrigeration, to understand What kind of vegetables it is, such as garlic moss or green vegetables can be stored for a short time, but for potatoes or beans, etc., they can maintain freshness for a long time.

It can be stored from 0 to minus 4 degrees for half a year.

Hello, I have to put the radishes in the cold storage, how can the goods taken out are all water, how can there be no water.

1. Soil pit storage: first remove the top and roots of the white radish, if there is a pit of insect damage or cracks that need to be removed, and then almost prepare a one-meter-high and one-meter-wide soil pit, put the processed radish in, bury the letter with the root facing up and lean on the pit wall with the top facing down, arrange it in turn, and then sprinkle the soil pit with soil. If the pit is too dry, you can add some water to moisten it.

2. Water tank storage: Prepare a clean water tank, then fill it with clean water, then add the cleaned radish to the periphery of the tank, and then cover it with wet soil.

3. Refrigerated preservation: Wrap the processed white radish in white newspaper and place it in the refrigerator or cold storage for about a week.

4. Freeze preservation: first peel the white radish and cut it into uniform pieces, then add it to the fresh-keeping bag and put it in the refrigerator to freeze.

5. Cooking and freezing: In order to save the time of the next stewing, the white radish can be frozen after cooking, or it can be stored together with the stewing juice, so that it can be eaten directly after being taken out and heated when eating, which saves time and effort, and is more convenient.

6. Dry preservation: The dry preservation here is to preserve the white radish after drying, cut the white radish into shreds after processing, and then put it outdoors to expose to the sun, and then take it indoors at night, so that it can be stored for about four or five days, and then sealed and stored in refrigeration, which can be stored for about half a year.

7. Pickled preservation: This method is also a more commonly used preservation method, the white radish is salted with salt and then added to the refrigerator for refrigeration and preservation, which can be stored for about a month.

The suitable storage temperature of carrots is 0 1, and when the predetermined loading capacity is reached, the storage temperature is required to reach the specified storage temperature within 48 hours. The storage temperature is required to be stable throughout the storage period, and the fluctuation does not exceed 1. If the storage temperature is higher than 2, it is easy to germinate, and if it is lower than 0, it is easy to freeze, and after freezing, it will not only lose quality, but also perish.

Once the carrots have reached the required storage temperature, the relative humidity in the storage room needs to be managed. Suitable for carrot storage with a relative humidity of 90-95%. If the humidity in the warehouse is insufficient, a cold storage humidifier can be used for humidification operation.

The hygrometer should be placed in a place that is not affected by condensation and air vibrations, and the accuracy of the instrument for measuring humidity is required to be 5%.

During the storage period, the carrots should be regularly sampled and inspected to check whether there is disease, cold damage, color change, water loss and rot, and if there is any abnormality, it should be removed in time. The fresh-keeping warehouse should be ventilated at least once a week when the temperature drops or in the evening.

First, the method of keeping carrots in cold storage: set up a plastic film tent in the cold storage.

1. Cut off the carrot stem plate before warehousing, and put it on the surface of the warehouse after selecting a good one. Generally, the stacks are 2 meters long, 1 meter wide and 1 meter high, and each stack is 1000 kilograms.

2. After a period of heat dissipation and pre-storage, when the temperature of the storage and the temperature in the carrot stack drop to 0, it can be closed with plastic film. The volume of the plastic film tent is slightly larger than the stack, and the void in the tent is about 50%. The tent is pressed with wet soil around it to keep the temperature in the warehouse about 0.

3. After a month after the closure, when the oxygen content in the tent is 6 8% and the carbon dioxide content is about 10%, the account is opened for ventilation, and the quality inspection and selection are carried out at the same time.

Hello! Refrigeration can only be done in a fresh-keeping state. Vegetables generally cannot be quick-frozen, and after quick-freezing, the vegetables will slowly change color, soften, and finally deteriorate after thawing. Generally, it is packed in foam boxes, put into cold storage for freshness, and the general storage period is about 2 months.

1. Low-temperature cold storage storage, the carrots are packed in plastic baskets, stacked in a single row and multiple layers in the warehouse, keeping the cold storage temperature at 1, the relative humidity is about 95%, and the carrots are ventilated once every 3 days, which can be stored for 5 to 6 months. The use of cold storage can be used to control the storage environment with a more combustible effect, and effectively inhibit the decay and deterioration of carrots. Although the cost of cold storage is high, the storage effect is good and the operation is simple.

2. Modified atmosphere preservation refers to the effect of fruit and vegetable preservation by adjusting the content of carbon dioxide and oxygen in the warehouse. By preserving their freshness in a modified atmosphere, carrots can be stored until May of the following year, when they retain their tender taste. Before being stored in a modified atmosphere, the carrots need to be properly dried to evaporate the moisture on their surface, and then packed into a frame for palletizing.

During the storage period, the oxygen in the tent is controlled at 2 5%, and the carbon dioxide is controlled below 5%. The temperature in the warehouse is 1, and the temperature of the warehouse should not fluctuate too much during storage to prevent decay caused by condensation.

3. Suitable for the north with low temperature in winter, before the carrots are stored, the bottom of the cellar needs to be disinfected, and the bottom is covered with a layer of fine sand of about 7cm, and then the carrots are stacked, the stacks should not be too high, and there should be gaps between the piles to facilitate heat dissipation and ventilation. The carrot is stored for 10 days in the early stage, and ventilation should be carried out every day for 3 hours, and then the cellar mouth can be sealed tightly with straw and fine sand. This method allows carrots to be stored for about 5 months.

4. The ditch is selected to be higher terrain, ventilated, not easy to seepage, and the ditch is dug at the place where the soil is compact, with a depth of 1 meter and a width of 1 meter. After digging, sprinkle quicklime on the bottom and four walls for disinfection, the outdoor temperature should be 0 5 when storing, the bottom of the ditch is spread with a layer of thicker fine sand, the carrot head is facing down, the root is facing up close to the yard row, and then covered with subsoil until the carrot is completely covered, so repeatedly stack the layer, and finally cover a layer of straw on the top layer again. When the temperature is low, an appropriate amount of water can be poured to keep a certain humidity in the ditch.

This method can be stored for about 4 months.

Summary. Hello, dear. It is normal for large radishes to be placed at minus a few degrees in the cold storage The answer is: radishes are afraid of freezing, and the minimum can be minus 3.

Hello, dear. It is normal for large radishes to be placed at minus a few degrees in the cold storage The answer is: radishes are afraid of freezing, and the minimum can be minus 3.

Dear, radish is a cruciferous family, radish is a biennial or annual herbaceous plant, radish can resist the low temperature of minus 3 for a short time. Radish seeds can grow at 4 to 6 hours, the most suitable growth temperature is 20 to 25, and the suitable temperature for fleshy root hypertrophy is 13 to 20. Radish can't be frozen at minus 5 degrees, radish is a semi-cold-resistant vegetable, and it is definitely not possible to grow at minus 3 degrees, and storage is more suitable for 0 5 degrees.

In situ winter storage freshly dug fresh radish should not be turned many times, so as not to damage the skin of the radish surface, so that the skin of the radish when the pit is cleaned in the next year is black. Therefore, we should advocate "one digging, two cutting, and three releases". It is best to hide in the radish field in winter to reduce turning, avoid transportation, and maintain the brightness of the skin of the radish.
