Dehydration Vegetable

Dried vegetable have fresh color, aroma, taste, shape and quality, and are easy to store. In the peak season of vegetables, vegetables in surplus areas are processed into dehydrated vegetable and sold to areas where vegetables are lacking, so that not only can you eat what you want in every season. The taste and quality of the food do not change, so how do we dry vegetable? Next I will share with you dehydrate vegetable process.

The first step: raw material selection

Choose vegetable varieties with rich meat quality. Before dehydration, vegetables should be strictly selected, and the parts with diseases, insects, rot and shriveled parts should be eliminated. 80% of the maturity is appropriate, overripe or underripe should also be picked out. Except for melons, the seeds of which are removed, other types of vegetables can be washed with clean water, and then placed in a cool place to dry, but should not be exposed to the sun.
The second step: cutting, blanching
The washed raw materials are cut into slices, wires, strips and other shapes according to product requirements. When pre-cooking, it varies according to the raw materials. For those that are easy to cook, put them in boiling water, and for those that are not easy to cook, put them in boiling water (the water temperature is generally above 150 ℃) and cook for a while. The general blanching time is 2 to 4 minutes. Leafy vegetables are not blanched.

The third step: cooling, draining

Precooked vegetables should be cooled immediately (usually with cold water) to quickly reduce to room temperature. After cooling, in order to shorten the dehydration time, a centrifuge can be used to shake off the water, or a simple manual method can be used to squeeze it.

Step 4: Vegetable dehydration

Put the processed vegetables on a clean tray, and then place them in a ventilated place under the sun. During the dehydration process, we have to turn the vegetables over from time to time to ensure that the vegetables can be better dehydrated.
However, sun dehydration is susceptible to weather, and dried vegetables are susceptible to contamination. Long dehydration times usually take a week. The moisture content of dried vegetables cannot be controlled, and the dehydration of various parts of the vegetables is uneven. Therefore, if we need to dry a large number of vegetables, the method of dehydration in the sun is too time-consuming, so I recommend using a professional vegetable dehydrator. Using a professional dehydrator is easy.

Dehydration high-yield vegetables

Put the vegetables into the material tray, insert the material tray into the material cart and push it into the dehydration room, and close the sealing door to start dehydration 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 dehydration time is about 8-10 hours to complete a batch.
Dehydration vegetable machines
Next I will introduce you to some vegetable dehydrators. We determine different temperature, time, color and moisture content during dehydration according to different varieties. I'm bringing you three vegetable dehydrators - mesh belt vegetable dehydrator,vegetable dehydrator room and all-in-one vegetable dehydrator.
In terms of output, the continuous mesh belt vegetable dehydrator machine is suitable for manufacturers with large output. Its output is 300-2000kg/h. The output of the vegetable dehydrator room machine is smaller than that of the mesh belt vegetable dehydrator machine, and the output is 100-5000/batch. The output of the all-in-one vegetable dehydrator machine is the smallest, and its output is 100-1500/batch. It is suitable for agricultural plants or small processing plants. Oven length and mesh belt layers can be customized. We can choose and match them reasonably according to our own processing requirements.

1. All-in-one vegetable dehydration machine

The first vegetable dehydrator machine is the all-in-one vegetable dehydrator machine with the smallest yield.
The dehydration principle is the same as that of the vegetable dehydrator room machine. The all-in-one vegetable dehydrator machine is equipped with a cart with trays and tray racks. When dehydration vegetables, we put them in trays, put them on the tray racks of the cart, and then push them into the vegetable dehydration chamber for dehydration.
The heat source of the vegetable integrated dehydrator 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 dehydration and processing of vegetables. The operation of this all-in-one dehydration unit is relatively simple, simply plug in and dry.

Components of all-in-one vegetable dehydration machine

One set all-in-one vegetable dehydrator 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 vegetable all-in-one machine has compact structure, good energy-saving effect, wide application range, high dehydration quality, convenient operation, simple installation and disassembly. It is the best dehydration equipment for small businesses, dehydration experiments and scientific research. The user only needs to connect the power to use, it is the easiest to operate vegetable dehydrator.

Advantages of all-in-one vegetable dehydration machine

1. Stainless steel 304 material. The whole machine uses stainless steel material, can work a long time, and keep better heat preservation, bottom have wheeler, can move easily.
2. Great energy saving. Heat pump system design, low energy consumption, can save 75% energy than traditional electricity element heating.
3. Wide application easy operation. Fit for wide application, seafood, fruit, vegetable, spice, herbs, etc all can use it to dry.
4. Gentle dehydration. Temperature range 40-80°C, low temperature dehydrate processing can better keep material nutrition, during dehydration, no need to move the machine.

2. Vegetable dehydration room machine

The second type of dehydration is the vegetable dehydrator room.
The vegetable dehydrator room machine is equipped with a trolley with trays and tray racks. When we dry the vegetables, we put the vegetables in the tray, on the tray rack of the cart, and push it into the vegetable dehydration chamber to dry. Vegetables are putted on the shelf car and enter the closed cycle dehydration room for dehydration without any pollution in the process. The heat source of the vegetable dehydrator room 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 dehydration and processing of vegetables.

Components of vegetable dehydration room machine

One set vegetable dehydration room machine contains: heat pump dehydrator host, dehydrator chamber, fan frame with fan, trolley with tray. The dehydrator chamber is used 100mm polyurethane insulation board, supporting 304 stainless steel trolleys and trays. Put the vegetables into the material tray, insert the material tray into the material cart and push it into the dehydration room, and close the sealing door to start dehydration 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 dehydration time is about 8-10 hours to complete a batch.

3. continuous mesh belt vegetable dehydration machine

Lastly, let's take a look at the continuous mesh belt vegetable dehydrator machine with the largest output. Mesh belt vegetable dehydrator machine have a wide range of heat sources such as coal heating, gas heating, steam heating, biomass pellet heating or electric heating. It is a multi-layer continuous dehydration structure. When dehydration vegetables, just put the vegetables in the feeding port, and the vegetables will enter the dehydrator with the feeding conveyor for dehydration.
Vegetables are dried and dehydrated layer by layer from top to bottom. The dehydration speed is fast and the production efficiency is high, which is very suitable for the dehydration and processing of large quantities of vegetables.
