Vacuum packing machine price and vacuum dryer price comparison
Vacuum packing machine price and vacuum dryer price comparison. Vacuum packaging machine packaging and vacuum dryer or different. Vacuum contact box dryer is a drying machine operated under the condition of vacuum sealing. There is a fixed tray inside the vacuum drying box, on which various types of heater parts are fixed, such as sandwich heating plate, heating column tube or coil tube. The dry material is placed in the moving tray, and the tray is placed on the heater. When the heat source enters the heater part, the material conducts heat transfer by means of contact conduction. The steam generated during the drying process is carried away by the outlet connected condenser or vacuum pump. If the steam contains recycled materials such as essence, the inter-wall condenser is used.

The drying plate used in the box is usually made of stainless steel plate or aluminum plate vacuum drying box is generally intermittent operation, heater pieces and materials between the plate should be in good contact as far as possible, from this point of view, the surface of the sandwich heating plate smooth more favorable, but its pressure resistance than tube type poor. In order to make the products after the vacuum drying can be used as devices in time and heater parts at the same time, the purpose can be achieved by replacing the heating agent with water. Different equipment is required to vacuum or dry the food in the food pack.

The liquid is first stirred and mixed with air or a gaseous substance such as ammonium bicarbonate is added, and then heated by contact, the gas expands under reduced pressure, forming a foam layer that can be controlled by vacuum. The foam layer dry products have the advantages of loose organization and good solubility. Therefore, the foam vacuum drying method is often used as a simple method of making instant food without condensing. Cold water, such as fruit powder, instant coffee, instant tea, etc.

The main point of foam vacuum dryer operation is that, when the initial drying water is more and liquid volume, viscosity is not high, not high vacuum operation, otherwise heating steam foam layer foaming rise is very high, overflow out of the disk, and fly a water at this time bubble is easy to burst, loss should be retained to the later foaming amount of gas. When the slurry is dried to the degree of vacuum drying box, the vacuum pump bubble produced by raising the vacuum degree at this time has a certain fastness and is not easy to break, forming a stable honeycomb framework for further drying.
