Abstract
The invention discloses a drying device which comprises a vacuum box and a vacuum pump, wherein an infrared heating panel is arranged in the vacuum box; the vacuum box is provided with a gas outlet and a gas inlet, wherein the gas outlet is connected with the vacuum pump; the infrared heating panel is arranged near the gas inlet and is used for heating gas passing through the gas inlet. As the infrared heating panel is arranged in the vacuum device, the heating temperature in the vacuum box is limited at 30-40 DEG C, so that to-be-dried food can be dried at low temperature, and the quality of the food is not influenced; in addition, the food is dried at a vacuum state, so that the surface of the food is not easy to harden; the drying speed is rapid, and the food drying speed can be increased by 10-15 percent.
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 the infrared heating panel 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 infrared heating panel 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 the infrared heating panel 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 infrared heating panel 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 infrared heating panel 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, and at first the air that enters vacuum tank 1 from micropore passes through infrared heating panel 3, and the food of then flowing through and being dried plays the effect of dried foods; 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, guarantee so the interior food of vacuum tank 1 uniform drying from the inside to surface.
Control the degree of heat of infrared heating panel 3, making the temperature in described vacuum tank is 30 ℃～40 ℃, prevents that excess Temperature from affecting the quality of food simultaneously.
Come dry Ipomoea batatas, banana with drying device of the present invention, in dry 2hr left and right, material moisture is reduced to 12%.
