Microwave drying equipment for jujube is a new type of energy-saving, environmental-friendly and efficient processing equipment for jujube. Through drying, the effect of drying and sterilization of jujube can be achieved. After drying, the color and nutritional components will not change, and the taste is excellent. It is the preferred equipment for all jujube processing factories.
complete set of equipment for cleaning and drying jujube
complete set of equipment for cleaning and drying jujube is composed of classifier, high-pressure bubble cleaner, brush cleaner, hoist, microwave drying sterilizer and other equipment. High-pressure bubble cleaning and spraying are used to remove impurities by brushing and enter the microwave dryer. The treated fruit surface is bright and uniform in size; it is cleaned according to national standards and export standards; it can increase added value of fruit, reduce water loss and prolong shelf life; it can be equipped with packaging machine to realize automatic production line.P>The equipment has high automation, high production efficiency, good cleaning effect, wide cleaning range, high cleaning degree and no damage to cleaning materials. Dazao is the ideal choice for deep processing merchants. It is also an ideal equipment for cleaning vegetables, mushrooms and aquatic products.

Microwave jujube drying equipment production line
Evaporation is the main method to achieve drying. Traditional drying methods include heat conduction, convection and convection. The method of thermal radiation provides the kinetic energy of water evaporation to the product. Microwave drying technology is to convert the energy of electromagnetic field into the kinetic energy of material molecules in an instant, that is to say, the material itself absorbs microwave energy to generate heat, so that water can be evaporated. Because of the penetration of microwave heating, microwave heating is actually a kind of three-dimensional heating, that is, both inside and outside the product are heated at the same time, the combination of hot air and microwave drying can make use of their respective advantages. It has the advantages of short acquisition time, high speed, low temperature sterilization to maintain nutrient composition and traditional flavor, energy saving and quality improvement. The quality of jujube dried by microwave dryer:
1. The moisture content of jujube dried from 28% to about 10%. The type of jujube dried by microwave is full, the color of jujube is unchanged, and the shelf life is prolonged.P>2. The big jujube slices produced by microwave are crisp, tasty and the color is the same as the original jujube, which has the most market value. Characteristics of microwave drying equipment:
1, even heating: Because microwave acts on water molecules, the part with high moisture content absorbs more microwave power than the part with low moisture content. This is the characteristic of selective heating, which can be used to achieve uniform heating and drying.
2, High Efficiency and Energy Saving: Microwave acts directly on the material, so there is no additional heat loss. The air in the furnace and the corresponding containers will not heat, so the thermal efficiency is very high, the production environment is also significantly improved. Compared with far-infrared heating, it can save 30% electricity.
3, high efficiency and short time: Because microwave heating does not need the process of heat conduction, microwave penetrates the object from different directions and dries the material uniformly from inside to outside in a very short time, which effectively shortens the drying time.P>4, easy to control: Compared with conventional methods, microwave operation is simple; microwave power can be adjusted, transmission speed can be adjusted.
