Abstract
The invention discloses a drying device. The drying device comprises a vacuum box and a vacuum pump, wherein the vacuum box is internally provided with an electrical heating pipe; an air outlet and an air inlet are formed in the vacuum box, the air outlet is connected with the vacuum pump, and the electrical heating pipe is arranged on the neighborhood of the air inlet and can heat the gas which passes through the air inlet. The drying device provided by the invention has the advantages that a vacuum device is internally provided with the electrical heating pipe, the heating temperature in the vacuum box is limited by 30 DEG C-40 DEG C, a condition that the dried food is dried under lower temperature is guaranteed, and the quality is not influenced; the dried food is dried under vacuum, the surface of the dried food is not easy to harden, the drying speed is rapid, and the drying speed of the food is improved by 10%-15%.
Description
Technical field
The present invention relates to the food processing equipment technical field, especially a kind of food drying device.
Background technology
Food drying method adopted the natural air drying mode in the past, and the existing hot blast that adopts drying plant to produce is dried.These two kinds of traditional drying modes are all first by the food surface drying, even reach the sclerosis stage, could carry out food inside dryly comparatively up hill and dale, cause drying time long, and the dried foods mouthfeel is poor; And heated-air drying can affect the taste of food, change the problems such as true qualities of food.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of drying device, dry rear food surface is non-sclerous, and mouthfeel is good.
In order to realize the foregoing invention purpose, the invention provides following technical scheme: a kind of drying device, comprise vacuum tank and vavuum pump, be provided with electric heating tube in described vacuum tank; Described vacuum tank is provided with gas outlet and air intake, and described gas outlet is connected with described vavuum pump; Described electric heating tube is located near described air intake, to passing through the gas-heated of described air intake.
Further, the pressure in described vacuum tank is 20～300Pa.
Further, described air intake is micropore.
Further, the temperature in described vacuum tank is 30 ℃～40 ℃.
Compared with prior art, the present invention has the following advantages: be provided with electric heating tube in vacuum plant, and the heating-up temperature defined in vacuum tank is 30 ℃～40 ℃, the food of guaranteeing to be dried is dry at low temperatures, does not affect its quality; And dry under vacuum, surface is difficult for sclerosis, and rate of drying is fast, can improve food drying speed 10%～15%.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, describe the present invention, the description of this part is only exemplary and explanatory, should any restriction not arranged to protection scope of the present invention.
A kind of drying device as shown in Figure 1, comprise vacuum tank 1 and vavuum pump 2, is provided with electric heating tube 3 in described vacuum tank; Described vacuum tank 1 is provided with gas outlet 12 and air intake 11, and described gas outlet 12 is connected with described vavuum pump 2; Described electric heating tube 3 is located near described air intake 11, to passing through the gas-heated of described air intake 11.Described air intake 11 is micropore.
Because air intake 11 is the micropore setting, in the unit interval, air inflow is less than gas output, and make in vacuum tank 1 and show as vacuum state, be 20～300Pa.
Control the degree of heat of electric heating tube 3, making the temperature in described vacuum tank is 30 ℃～40 ℃, prevents that excess Temperature from affecting the quality of food simultaneously.
Select Ipomoea batatas, banana, carry out respectively drying in apparatus of the present invention, dry 2hr left and right, material moisture is reduced to 11%.
