Heat Pump Food Drying Machine

Industrial Heat Pump Food Drying Machine Introduction

This industrial food drying machine is the professional machine to remove material moisture as quickly as possible at a temperature that does not seriously affect the flavor, texture, and color of the food. The industrial hot air circulation drying machine is featured with axial flow fan, automatic constant temperature control system, and equipped with computer control system for selection.

Different from the small hot air drying machines, this large hot air drying machine, featured with more baking vehicles, is suitable for large-scale material drying production. This heat pump drying machine is suitable for drying materials that are mainly resistant to range of temperatures between 20-80 °C during the drying process, such as: wood, grain, seed, edible mushrooms, medicine, seafood, bacon, fruit and vegetables, tobacco leaf, paper and incense, etc.

♦ Wide application: a variety of materials can be dried like vegetables, fruits, herbs, mushroom and etc..

Characteristics of Heat Pump Food Drying Machine

Most hot air is circulated in the drying machine so that heat efficiency is high and the energy is saved. There are adjustable air distribution plates inside the oven. By using the forced ventilation function, the materials can be dried uniformly. The heating source might be steam and electricity. It is a versatile drying equipment that can be used for drying various materials. When you utilize the drying machine, please notice the following tips:
1. When the machine starts to work, if the temperature is too low in the beginning, microorganisms may survive and even grow before the food is adequately dried. If the temperature is too high and the humidity too low, the food may harden on the surface. This makes it more difficult for moisture to escape and the food does not dry properly. So in the drying process, you should pay attention to the temperature.
2. There should be sufficient space among materials on trays so that there is a uniform distribution of heat.

Choose Suitable Plates For The Heat Pump Drying Machine

The oven plate also named the oven tray is a significant part of the hot air drying process. There are two types of plates provided by us.
1. PP food grade plastic trays: low cost, suitable for all kinds of materials
2. Stainless steel mesh trays: suitable for higher hygiene requirements

Food Nutritional Changes Occurred During Hot Air Circulation Drying

♦ Calorie content: no change, but is concentrated into a smaller mass as moisture is removed.
♦ Fiber: no change.
♦ Vitamin A: fairly well retained under controlled heat methods.
♦ Vitamin C: mostly destroyed during the drying of vegetables.
♦ Minerals: some may be lost.
♦ Iron: not be destroyed by drying.
