Application of microwave drying and sterilization equipment in the nut industry

The nut series has high edible rate, 97% edible portion, 100% dried fruit and candied fruit, and low acid content, no hard and large seeds, so it is especially suitable for the elderly and children. Sweet, flat. It can replenish the spleen and stomach, moisten the lungs and pharynx, and relax the bowels. Nuts are rich in enzymes such as proteolytic enzymes, lipases, amylases and oxidases, all of which promote protein breakdown. Therefore, when people eat more protein-rich foraging, the fruit after cooking with nuts has a good effect to help digestion.

Introduction of Nut Microwave Drying and Sterilizing Equipment: Microwave drying is a new type of drying method. When drying, the microwave energy directly acts on the medium molecules to convert into heat energy. Since the microwave has the penetrating property to simultaneously heat the inside and outside of the medium, heat conduction is not required, so the heating speed is very fast, and the drying speed can be shortened for foods with water content below 30%. Hundreds of times. At the same time, regardless of any shape of the object, due to the simultaneous heating inside and outside the medium of the object, the temperature difference between the inside and the outside of the material is small, the heating is uniform, and the condition of external coke in the conventional heating does not occur, so that the drying quality is greatly improved. At the same time, microwave acts on bacteria and eggs, causing thermal effects and biological effects, blocking the metabolism of microorganisms such as bacteria to achieve the effect of sterilizing insecticidal eggs. Compared with other methods of bactericidal insecticidal eggs, the microwave equipment is fast and thorough, and will not damage the original nutrients of the fig, and achieve drying and sterilization at the same time.

Tunnel type microwave drying sterilization machine features :

1. The drying and sterilizing time is short, the temperature is low and uniform, and the aroma of the fig is thick and the color is bright;

2. Selective heating. Since the water molecules are good for microwave absorption, the portion with a high water content absorbs more microwave power than the portion with lower water content. This is the characteristic of selective heating, which can be used for uniform heating and uniform drying and sterilization.

3. The direction of dry and dehydrated water vapor is from inside to outside. Therefore, microwave drying can make the figs expand and become larger.

4, energy saving and environmental protection. The microwave acts directly on the material, so there is no additional heat loss, which can save more than 30% compared to other methods of drying sterilization. The production conditions of microwaves only require water and electricity, which is simple and convenient, and does not cause pollution.

5, advanced technology, flexible and simple operation, the power of the equipment is adjustable from 0 to the rated power, the microwave intensity in the cavity, the temperature is adjustable, the monitoring system displays the temperature inside the wall and the material process at any time. As long as 2-3 people can complete the drying and sterilization production of figs.

In addition, microwave equipment can also be used for sterilization of bagged or bottled nuts. Microwave penetration, can penetrate plastic bags or glass bottles for sterilization, microwave sterilization speed, mass production, can be sold after sterilization of packaged figs, no secondary pollution.
