[ Hot News of Food Machinery and Equipment Network ] With the approaching of the Spring Festival, many new year's goods markets are gradually lively, filled with a strong festive atmosphere. Many citizens have begun to buy New Year's goods, such as raisins. In recent years, with consumers' pursuit of food safety and quality, healthy and nutritious, high-quality raisins have become more and more popular in the market, and it has also pointed out the general direction of development for the raisin market. So, how to improve the quality of raisins and ensure the color, flavor and quality of raisins, the air energy heat pump dryer has something to say.

There are many types of grapes in China, such as seedless white, long-grain seedless white, seedless purple, seedless white chicken heart, etc. Among them, seedless white is a very important dry variety. It is understood that the production process of raisins mainly includes multiple steps of raw material screening, slag removal, cleaning, drying, classification, and packaging. However, the traditional raisin drying process mostly adopts natural drying, or uses drying promoters, which are not only greatly affected by the natural environment and have low drying efficiency, but also it is difficult to ensure the quality of raisins.
In addition, according to reports, traditional raisin drying is also a physical task. It needs to be turned continuously during the drying process, and the drying time is long. It takes about 30 days to dry in the shade, which takes time and effort. Generally, 4 pounds of fresh grapes can be made into 1 pound of raisins. Low drying efficiency. What is more interesting is that raisins are naturally dried. Although the traditional process is retained, after all, natural drying is mostly based on people's experience to control temperature and humidity. Sometimes temperature and humidity control is not allowed to directly affect the color, flavor and quality of raisins.
"The raisin system has high requirements on temperature and humidity. Realizing accurate temperature and humidity control can not only ensure the color and flavor of raisins, but also ensure the dry quality and taste of the product, and meet the consumer demand for high-quality raisins," said a raisin manufacturer.
Nowadays, with the improvement of China's science and technology level, the rapid development of food infrared drying, hot air drying, air energy heat pump and other technologies has driven the development of drying equipment to mature, and many innovations have emerged in the market.
Take air energy heat pump dryer as an example. This machine mainly uses the reverse Carnot principle to release high-temperature heat through refrigerant condensation and liquefaction, and then compresses it into a higher temperature air to heat the drying room through a compressor , thereby achieving the purpose of raisin production. In addition, the air-energy heat pump dryer has man-machine interface operation, PLC, temperature and humidity control systems, and the advanced heat pump system to control the temperature and the temperature and humidity sensors to support the multi-stage raisin with different temperature and humidity requirements to ensure the quality of raisins. .
With the increasing competition of the drying equipment market and the green development of "reducing energy consumption and reducing pollution", equipment with high energy consumption, high pollution, low efficiency, poor drying quality and low technical content will face in the future. The market is eliminated, and products with high technological content, high drying efficiency, good uniformity, low pollution and significant energy saving effects are more welcomed by the market. Therefore, energy saving and environmental protection will become the key to the transformation and upgrading of drying equipment manufacturing enterprises and increase market competitiveness.
According to the manufacturer, the dryers used before had high energy consumption, high pollution, low grape drying efficiency and poor quality. Later, an air-energy heat pump dryer was purchased, which greatly improved the drying efficiency of grapes, shortened the drying time, ensured the color, flavor and quality of raisins, and reduced energy consumption by more than 50%. It did not emit dust, Odors reduce pollution and reduce our pressure on energy conservation and environmental protection.
With the approaching of the Spring Festival, the raisins and other new year markets are gradually lively, highlighting the tremendous vitality of the consumer market. Coupled with consumers' pursuit of food safety and quality, the high-quality raisin annuals market will be more favored by the market. With the promotion and application of new energy-saving and environmental-friendly air-energy heat pump drying equipment, the quality of raisins will continue to be strengthened, the color, flavor and quality of raisins will be improved, and the "safety on the tip of the tongue" will be protected, allowing people a happy New Year.
