Food Freeze Dryer For Home Use

Food Freeze Dryer For Home Use (Food Freeze Dryer) is a professional equipment for freeze-drying food. It converts the moisture in the food into water vapor by controlling parameters such as temperature and vacuum degree, and then discharges the water vapor from the food, so that the food can reach a dry state.

Advantages of Food Freeze Dryer For Home Use

① Keep food structure, nutrients and flavor substances basically unchanged, especially the retention rate of physiologically active ingredients
The highest, which is the main reason why some functional foods use freeze-dried food as the base material.
②The appearance is not dry and cracked, does not shrink, and maintains the original shape and color of the food;
③The product has no surface hardening, and the tissue is porous and spongy, so it has good rehydration performance, is convenient to eat, and can be restored after soaking, which determines its status in instant convenience foods;
④Light weight, resistant to storage, no special requirements on ambient temperature, when packing away from light and vacuuming and filling with nitrogen,
It can be kept for about 2 years under normal temperature conditions, and its storage, sales and other recurring costs are far lower than frozen foods.
Compared with canned food and frozen food, the recurrent costs of transportation and storage of freeze-dried food are lower, while freeze-dried food
The high value attached to the high quality of food can make up for the disadvantage of high cost, especially for high priced products.
For food materials, the cost of freeze-drying does not take a large proportion in the sales price of its products. Keep the original food shape, color,
Fragrance, taste, nutrition unchanged, good rehydration, light weight, and can be stored at room temperature. Freeze-dried food in International City
The price on the market is 4 to 6 times that of hot air dried food, and 7 to 8 times that of quick-frozen food.

Japan needs to spend about 100 billion yen to import freeze-dried food every year, and Hong Kong, Singapore and South Korea import freeze-dried food to 50 billion yen every year. Japan, the United States and Europe need about 6,000 tons of freeze-dried garlic powder every year. It can be seen that the international market for freeze-dried food is growing.

Composition of Food Freeze Dryer For Home Use


It is used to freeze the food, crystallize the water in it, and prepare for the subsequent freeze-drying process. Some manufacturers choose square bins (high space utilization rate), and some manufacturers choose round bins (low space utilization rate); generally, machines above 50 sq. The vacuum is hard to control.

Drying room

It is used for freeze-drying treatment, mainly including two links of heating and vacuum. Heating refers to converting the moisture in the food into water vapor by raising the temperature, and vacuum is to extract the water vapor from the food, so as to achieve the drying effect.

Cold trap

Cold traps are used to trap sublimated water vapor. The ice-catching capacity of the internal cold trap of the Freeze Dryer Food Machine directly affects the vacuum degree in the warehouse. In the early stage of freeze-drying, the amount of sublimation is large, which requires a strong ice-catching ability of the cold trap. As the amount of sublimation decreases, the demand for ice-catching ability of the cold trap also decreases. Some manufacturers use small compressors, cold traps are placed on the side, and the water catchment capacity is just enough, and some manufacturers have a relatively large water catchment capacity (some manufacturers have a 5-level machine with a water catchment capacity of 65kg, so the corresponding price will be relatively high) ;

Control System

It is used to control the temperature, vacuum degree and other parameters in the drying room to ensure the stability and safety of the whole process.

How to freeze dry candy?

Freeze dried candies have a stronger flavor and have a unique spongy texture, and most have a higher concentration of sugar after the candies have sucked out all the water during the freeze-drying process, so they're a little sweeter than what you'd normally eat.

how to freeze drying candy

The process of freeze drying candy:

Step 1: Cut the candy into small pieces.
Of course, not all candies need to be cut into small pieces. If the candy is larger, it needs to be cut, because the candy freeze-drying will expand. In addition, small pieces of candy can be freeze-dried faster and more efficiently.

Step 2: Pre-freeze Candy in a regular refrigerator
Because the freeze drying time will be very long, freezing the candy in the ordinary refrigerator and then putting it in the freeze drying machine will shorten the freeze drying time.

Step 3: Place candies on freeze drying trays and spread out evenly.
The candy must be spread out, because freeze-drying will cause the volume of the candy to expand exponentially. In addition, it should be placed evenly.

Step 4: Operate the freeze dryer to complete freeze drying.
The freezing process takes about 24-36 hours, and there are several factors that affect the final taste, such as the moisture content of the candy, whether it is pre-frozen, whether the freeze dryer is adequately sealed, etc.

how to freeze dry candy

Once freeze drying is complete, you can remove the freeze-dried candy and place it in airtight containers such as jars and airtight bags, which can be placed anywhere after being airtightly packaged.

*Most candies will expand to a much larger size, so be sure to spread them evenly in your freeze dryer, for larger candies you may need to cut them into small pieces before freeze drying.
*If you freeze-dry hard-shelled candies, they will expand to 2 to 3 times their original size and the shell of the candy will crack

The process of freeze drying candy is similar to dehydration, which is interesting because freeze-drying removes most of the moisture from the candy, so it tastes crunchier and has fewer calories.

Most candies can be freeze dried within 24-36 hours, and freeze dried snacks and candies are a great option if you want to start a small business. They are very tasty, very popular in the market, and because they are not common, they are also very expensive.

What other foods can freeze dryer machine freeze dry?

1.Freeze drying coffee

Freeze drying is a key step in the production of instant coffee. The process of freeze drying coffee is:
*The coffee beans are first roasted and ground, then dissolved in hot water to obtain a highly concentrated liquid, usually, the mass of the obtained coffee solution is about 15-30% of the coffee weight.
*After filtering, the coffee extract is dried to obtain solid soluble coffee.

*Freeze the liquid to about -40°C to form a thin layer before breaking it into small pieces.
*The pellets are then loaded into a freeze dryer.

2.Freeze-dried fruit

Fruit can also be freeze dried, but it may take longer, and freeze dried fruit has a long shelf life, which is a great way to store fruit.
Freeze dried fruit retains all the nutrients of the original fruit and can be enjoyed anytime, as long as you don't add anything during the freeze drying process. Freeze dried fruit is just as healthy as any other type of fruit.
1. Choose fruits with high water content, such as apples, grapes, peaches, pears, these are very popular fruits for freeze drying. Of course, some other fruits can also be freeze dried, such as: bananas, mangoes, kiwis, pineapples, can also be freeze dried.
2. Wash and dry the fruit, and remove the dirt on the surface as much as possible. If the surface of the fruit is not clean, it will affect the effect and taste of freeze drying.
3. Cut the fruit into pieces and place them evenly on the tray of the freeze drying machine. There should be space between the fruit pieces and they should not be attached to each other. Otherwise, the fruit may stick to each other during the freeze drying process.
4. Put the tray into the freeze dryer, start the machine, adjust the time, and start freeze drying.
5. When the time is up, turn on the machine and take out the freeze dried fruit pieces.
