Pineapple drying is mainly carried out by using the latest energy-saving and environmentally friendly dryer-heat pump dryer. It does not need to burn materials to provide heat to our equipment, but directly absorbs the air in the outside world, and then compresses the air into high temperature and high pressure gas, and then transfers our gas to the interior of our barn. Proceed to dry our pineapples.
Pineapple drying process
Our pineapple drying needs to be sliced during drying. Its drying can be divided into 5 stages for drying, and the temperature range is also adjusted in different stages.
The first stage: dry but not wet, the time is 1.5 hours, the temperature inside and outside is the same, and the temperature is 50 °C.
