Air source heat pump dryers are widely used in three major industries, which can be subdivided into many categories, especially the primary industry. According to the national economic industry classification, the sub-categories of heat pump drying applications in the primary industry agriculture include grains, tobacco, fruits and vegetables, edible fungi, flowers, tea, Chinese herbal medicines and aquatic products; the secondary industry industrial manufacturing heat pump drying application categories involve Printing, leather manufacturing, fireworks manufacturing, electroplating industry. Air source heat pump drying technology has been widely used in hotel services in the tertiary industry and in the sludge treatment industry in public facility management.
Heat pump drying method for peppers: The water content of pepper raw materials is very high, generally 75%^85%. Set the temperature of the Quaneng pepper dryer to 40℃-60 ℃ hot air drying, the relative air temperature is lower than 70% at first, and the relative air humidity drops to 52% after 5 hours, and after 2 hours, the relative air humidity is all lower than 40%. Therefore, the productivity of pepper drying operation is mainly determined by the temperature of the pepper itself, rather than the ability of hot air to carry and remove moisture. From the perspective of ensuring that the nutrients of peppers are not affected after drying and improving productivity, the temperature of the hot air for drying peppers is determined by 60 ℃ - 70 ℃ C is suitable.
Staged drying is currently the preferred method for drying peppers, that is, peppers with a moisture content of 75% to 85% are first dried to a moisture content of 50%, and then the second time is dried. After the second drying is completed, high-quality dried chili products can be obtained
