Description

Drying device for food production

Technical Field

The utility model relates to food processing equipment technical field, concretely relates to drying device for food production.

Background

In the food processing industry, a food drying device is a frequently used device, and most of the current drying devices adopt drying cylinder type drying, hot air type drying and far infrared drying methods. In the method, in the process of drying the food, water molecules on the surface of the food are brought away after contacting with hot air; meanwhile, as the hot air and the food are subjected to heat exchange, the moisture in the food is transferred to the surface of the food, and water molecules on the surface of the food are taken away by the hot air again. Such an outside-in drying manner by heat transfer is efficient in drying thin food, but it takes a long time to dry food having a certain thickness, and even there may be a case where the surface of the food has been dried and the inside of the food has not been heated.

SUMMERY OF THE UTILITY MODEL

In order to solve the defects of the prior art, the utility model aims to provide a drying device for food production, which can synchronously heat the interior of food and dry food with certain thickness and large volume more easily.

The utility model adopts the technical scheme as follows: a drying device for food production comprises a box body, a door, a heating device and a fan, wherein the box body comprises a shell, a heat preservation layer and an inner container, a drying disc, an air inlet, an air outlet and a microwave generating assembly are arranged in the inner container, and a temperature sensor is arranged at the air inlet; the fan is connected with the air inlet through an air inlet pipeline, and the heating device is arranged in the air inlet pipeline; the air outlet is connected with an air outlet pipeline, and a dehumidifying device is arranged at the tail end of the air outlet pipeline; the fan and the dehumidifying device are also connected through a loop pipeline.

Furthermore, the inner container is a metal inner container, a plurality of grooves are horizontally arranged on the inner wall of the inner container, and the drying disc is placed on the grooves. The metal inner container ensures that microwaves can be comprehensively reflected in the inner container, so that the microwaves are filled in the whole inner container space to heat the dried food in multiple directions.

Further, the drying tray is made of non-metal materials and materials supporting microwaves at the same time, and comprises glass, ceramics and plastics; preferably, the drying tray is made of plastic material, and the plastic material has lower microwave absorptivity.

Further, the heat preservation layer is a polyurethane heat preservation plate, preferably, the heat preservation plate is arranged between the shell and the inner container.

Furthermore, the door is also provided with a transparent observation window, and the drying state of the dried food can be checked through the transparent observation window when the door is used; preferably, the observation window is made of explosion-proof glass.

It should be noted that, when the microwave generating assembly works, the microwave generating assembly stops working only after the temperature inside the food is heated to the temperature of the hot air during drying, and preferably, the working time of each microwave generating assembly is set to be 5 to 10 seconds.

Has the beneficial effects that:

the utility model provides a pair of drying device for food production sets up the microwave generation subassembly in that the stoving box is inside to and set up the return circuit of hot-air of drying. When food with certain thickness and larger volume is dried, the microwave generating assembly is started to generate microwave to heat the food while the food is dried by hot air, so that the food is internally heated when being dried at first, the waiting time for the moisture in the food to be transferred to the surface of the food to be taken away is reduced, the food drying time is shorter, and the possible condition that the surface of the food is dried and the inside of the food is not heated is avoided.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments of the present invention belong to the protection scope of the present invention.

As shown in fig. 1, the drying device for food production comprises a housing 11, a heat insulating layer 12 and a liner 13 forming a box body 1, a door 2 on the box body 1, a drying disc 5 arranged in the liner 13, an air inlet 6, an air outlet 7, a microwave generating assembly 8 arranged at the top of the liner 13, a temperature sensor 9 arranged at the air inlet 6, a fan 4 connected with the air inlet 6 through an air inlet pipe 61, a heating device 3 arranged in the air inlet pipe 61, an air outlet pipe 71 connected at the air outlet 7, and a dehumidifying device 72 arranged at the tail end of the air outlet pipe 71; and a return conduit 67 connecting the fan 4 and the dehumidifying apparatus 72.

In this embodiment, the inner container 13 is made of stainless steel, and a groove 131 is formed on the inner wall of the inner container 13 for placing the drying tray 5.

In the present embodiment, the drying tray 5 is made of a microwaveable plastic.
