Heat Pump Dryer for Food

The heat pump dryer has a wide drying range. The closed-loop drying will not pollute the food, and it has high drying efficiency, energy saving and environmental protection. It is the best choice for drying businesses. Generally speaking, heat pump dryer is divided into two types, one is a food dryer room and the other is a all-in-one food dryer. Next, I will introduce the details of the components, drying principles and technical parameters of these two heat pump dryers.

1. Heat pump dehydrated food machine

The heat pump dehydrated food machine is equipped with a trolley with trays and tray racks. When we dry the foods, we put the food in the tray, on the tray rack of the cart, and push it into the dehydrated food chamber to dehydrate. Foods are putted on the shelf car and enter the closed cycle dehydration room for dehydrated without any pollution in the process. The heat source of the heat pump dehydrated food machine is air. The heat in the air is absorbed by the heat pump compressor. After being compressed and released, a large amount of high-temperature hot air can be obtained, so as to achieve uniform drying and processing of foods.

Components of heat pump dehydrated food machine

One set heat pump dehydrated food machine contains: heat pump dehydration host, dehydration chamber, fan frame with fan, trolley with tray. The dehydration chamber is used 100mm polyurethane insulation board, supporting 304 stainless steel trolleys and trays. Put the foods into the material tray, insert the food tray into the vegetable cart and push it into the dehydration room, and close the sealing door to start drying production. The dehydration temperature range is 65 ℃ - 85 ℃, and the dehydration temperature is divided into different temperatures, and the temperature is gradually lowered. Generally, the drying time is about 8-10 hours to complete a batch.

The working principle of heat pump dehydrated food machine

The heat pump food dehydration room uses the reverse Carnot principle to let the hot air circulating blower dehydrated food. Compressor and other equipment make up the refrigerant circulation system. The fan impeller rotates, the outside air enters the oven, passes through the heater, forms hot air, and then enters the studio through the gap of the air distribution plate, and a large amount of hot air in the circulating flow continues to enter the new air inlet for supplementation. The moisture discharged after recovery is discharged from the exhaust port. The whole cycle makes the food heated evenly and achieves the purpose of dehydartion.
Determine different temperature, time, color and moisture content during drying according to different varieties. It is better for the food dehydration machine to use the air energy heat pump drying system, and the heating of the air energy is a slow increase, which is more reasonable for the drying of foods, and can maintain the original tissue fibers and nutrients of the foods, and through the compressed air , The whole process of extracting air heat energy does not contain harmful substances, and it is also more energy-saving and environmentally friendly.

The drying machine can be equipped according to the user's requirement and the production demands.

Advantages of heat pump dehydrated food machine

1 Wide application. Suitable for vegetable, fruit, seafood, spice etc different kinds of material.
2 High drying capacity. Each hour can drying 3-4kg water.
3 Better drying effect. Can better keep material shape , color , nutrition etc.
4 Simple operating. PLC touch screen control panel , can set up temperature, humidity in advance  
5 Low energy consumption. Heat pump system, can save 70% energy.

Other application areas of heat pump dehydrated food machine

Heat pumps can be used in many applications, in addition to drying vegetables can also be used in agriculture, industry, seafood, grain, herbal medicine, construction, paper products, condiments, mineral industry, etc.
1. Dried vegetables such as radish, lettuce, pumpkin, carrot, spinach, cassava, etc.
2. Fruits such as apples, lemons, mango slices, dried longan, dried longan, etc.
3. Dried meat such as sausage, beef, duck, ham, etc.
4. Others it can dry noodles/wooden/incense/herbs/floss etc.

2. All-in-one food dryer machine

The third food dryer machine is the all-in-one food dryer machine with the smallest yield.
The drying principle is the same as that of the food dryer room machine. The all-in-one food dryer machine is equipped with a cart with trays and tray racks. When drying foods, we put them in trays, put them on the tray racks of the cart, and then push them into the food drying chamber for drying.
The heat source of the food integrated dryer is air energy. The heat in the air is absorbed by the heat pump compressor. After compression and release, a large amount of high-temperature hot air can be obtained, so as to achieve continuous and uniform drying and processing of foods. The operation of this all-in-one drying unit is relatively simple, simply plug in and dry.

Components of all-in-one food dryer machine

One set all-in-one food dryer machine contains: power jack, water outlet,exhaust air outlet, supporting wheels, PLC controller pancl, door lock, observation window,circulating air inlet, outlet for hot and dry air, PP tray, stainless steel tray, supporting racks for trys. The food all-in-one machine has compact structure, good energy-saving effect, wide application range, high drying quality, convenient operation, simple installation and disassembly. It is the best drying equipment for small businesses, drying experiments and scientific research. The user only needs to connect the power to use, it is the easiest to operate food dryer.
