FAQ for heat pump industrial dehydrator machine
1. What is the maximum moisture content required for air dryer to dry corn?
A. Corn drying generally uses tower type grain dryers, such as the Zhengxu Air Energy Grain Dryer, which is an automatic continuous drying complete set of equipment and can enjoy agricultural machinery promotion subsidies. The moisture content of the dried material wet corn is generally between 14-16.5% due to different origins and weather conditions. After drying, the moisture content of the product generally does not exceed 9.5%, and the humidity required for corn preservation should not exceed 10%.
2. The current situation and application of heat pump drying technology in which industries?
A. The heat pump drying technology is still in the hands of a few professional manufacturers of heat pump dryers (such as the well-known heat pump dryer brand Zhengxu). There is still a long way to go to achieve the mastery and comprehensive popularization of this technology by most heat pump manufacturers, which requires strengthening industry cooperation and communication. Currently, the main application fields of air heat pumps are agricultural and sideline products such as tobacco, fruits, mushrooms, wood, and food products such as betel nut Preserved meat, beef, fresh fish, Rice noodles, noodles, starch, etc., Chinese medicine materials: such as medlar, gastrodia elata, panax notoginseng, maka, ophiopogon japonicus, etc., industrial products: such as metal parts, electronic products, paint, etc., special industries: such as explosives, fireworks, etc.
3. How to build a Cantonese style cured meat baking room, including precautions such as material selection, construction steps, and on-site installation
A. Guangzhou style cured meat has a unique color, aroma, and flavor, so its drying process is different from smoked cured meat. The use of an air energy heat pump to dry Guangzhou style cured meat is one of the highlights of Zhengxu's heat pump drying technology. Guangzhou style cured meat is divided into two processes: drying and air drying, with air dried cured meat being more complex and famous. However, due to its involvement in production, cost, benefits, and many other aspects, the main products sold on the market are still dried cured meat. The Guangzhou style cured meat drying and drying room must ensure that all components are non-toxic and odorless, and fully comply with hygiene standards. The substrate is generally made of polyurethane composite stainless steel (food grade) insulation board, and the heating temperature of the heat pump should not be too high. The drying time is generally between 24 and 30 hours, and the key feature of design and installation is to strictly ensure the coordination of air volume, temperature, humidity, and other factors in the drying room and follow specific process requirements, Unify the heating surface of dried cured meat, ensure the gradual release of meat aroma, and meet the requirements for the color, aroma, and appearance of the dried product.
4. What are the applications in the northern region?
A. Due to the low winter temperatures in the northern region, only a few manufacturers have tried air drying in the northern region. The Zhengxu integrated heat pump dryer is mainly designed for the drying process in cold northern regions. Currently, successful cases mainly include the drying of goji berries in Ningxia, the drying of dates in Henan and Shandong, the drying of rice and wheat in Hebei, Anhui, and the drying and insulation of many industrial products. According to industry experts, The air energy heat pump drying technology is also widely used in cold regions of the north, and has huge market development potential.
