Problems solved by technology

[0004] In order to achieve the purpose of oxygen isolation, vacuum drying is generally used at this stage, but the cost of vacuum drying is high, the efficiency is low, and there are high requirements for equipment, so it is difficult to realize continuous industrial production; on the other hand, the existing drying equipment There are also technical application obstacles such as high energy consumption and difficult heat transfer and penetration, so the existing technology cannot meet the drying requirements of lilies, which are prone to enzymatic and oxidative browning.

Abstract

The invention discloses a heat pump type waste-heat recovery microwave oxygen-insulation drying machine. A tunnel-shaped glass cover is fixed on a base plate of a conveying belt, an upper plate of the tunnel-shaped glass cover is provided with ventilation screen holes and covered with a glass packing ring, a microwave unit is arranged above the packing ring, materials on the conveying belt is heated by microwaves in the glass cover and reach the conveying belt of an insulation tank body through a slide plate, a cutoff curtain and a blower are arranged at an outlet of the glass cover, and another cutoff curtain is arranged at an inlet of the glass cover. An exhaust pipe is communicated with a microwave unit above the ventilation screen holes, and heat in the exhaust pipe is transferred through a heat pump and then enters a hot air drying system of the insulation tank body. By the heat pump type waste-heat recovery microwave oxygen-insulation drying machine, continuous efficient enzyme deactivation and synchronous oxygen-insulation drying are realized in a non-vacuum condition, and industrialized implementation is facilitated. The heat pump is low in power consumption and high in heating coefficient, waste heat can be completely recovered, and cost and energy consumption are reduced. The packing ring insulates the air and timely evaporation of moisture is guaranteed. Hot-air countercurrent is kept in uniform quality, and the drying machine is particularly suitable for drying agricultural products which are prone to enzyme promoting and high-temperature oxidation browning and is wide in prospect.

Description

technical field [0001] The invention relates to a heat pump type tail heat recovery microwave oxygen insulation dryer. Background technique [0002] Drying is to remove the moisture in the material, which is widely used in food, chemical industry, agricultural product processing, biological product processing and other fields, and is a unit operation with high frequency of use. [0003] Drying can be carried out in the air or in the sun under natural conditions, but for industrial production, drying is generally carried out in a dryer. For agricultural products such as lilies that are prone to enzymatic and oxidative browning, they generally need to be boiled at high temperature first. Drying is carried out after enzyme-killing treatment, and drying also has special requirements, that is, it is hoped that oxygen should be separated while heating (the speed of oxidative browning will be greatly increased during heating), and fast and efficient drying can be carried out under ...
