Problems solved by technology

This is also difficult to achieve with hot air drying
Since the main purpose of the above research is to explore the process parameters of the far-infrared vegetable dehydration process, the technical solutions of fixed drying oven, multi-layer tray loading, manual turning, and intermittent heating and drying are all used, which are currently only in the experimental stage. stage
This solution needs to open the door when turning and changing the material, resulting in large heat loss, troublesome operation and low efficiency
Therefore, it is difficult to use in actual production

Abstract

The far infrared vegetable dewatering apparatus includes drying cabinet, transmission mechanical,, conveying mechanism and heater. The drying cabinet has material feeding port and induced draft port in the top and discharge port and air intake in the bottom. The present invention features that the drying cabinet is separated with partition boards into several layers with separated conveying mechanism, transmission mechanism, heating unit and guide board. The present invention has small size, convenient operation, fast drying speed, high heat efficiency and low power consumption, and the dried vegetable product has bright color and high quality.

Description

Technical field [0001] The invention provides a far-infrared vegetable dehydration device, in particular to a device for dehydrating and drying vegetables by using far-infrared radiation. Background technique [0002] At present, the commonly used vegetable dehydration and drying form in China is hot air convection drying. In order to ensure the drying speed, the temperature of the hot air is generally higher, and the drying is carried out under normal pressure, so it is easy to cause a large loss of organic matter and nutrients such as Vc in vegetables due to oxidation. At the same time, too high temperature will also form a hard shell on the surface of the material, hindering the outward migration and evaporation of internal moisture. If the air temperature is lowered, the heat transfer rate will slow down and the drying time will be longer. Not only can not guarantee product quality, but also greatly reduce production efficiency. Simultaneously, also can cause the colo...
