The best drying technology for macadamia nuts:
The drying temperature and time of fruit with shell are as follows: 30 ℃ (2 ~ 3 d) ~ 38 ℃ (1 ~ 2 d) ~ 45 ℃ (1 ~ 2 d) ~ 50 ℃ (dry until the required moisture content). The drying time is affected by the following conditions: the initial humidity of the fruit, the relative humidity of the air, and the final moisture content of the dried fruit. If the initial humidity, the relative humidity of the air and the water content required to be achieved are higher, the time required will be longer and the reverse will be shorter, depending on the specific circumstances.In addition, the initial drying temperature should be determined by the moisture content of the nuts with shells. If the moisture content of the nuts is 25% -28%, the drying temperature should not exceed 30 ℃; if the moisture content of the nuts is 15% -20%, the drying temperature should not exceed 38 ℃; if the moisture content of the nuts is 10% -15%, The drying temperature should not exceed 45 ℃; if the moisture content of the kernel is 7- 10%, the drying temperature should not exceed 50 ℃; otherwise, during baking, the shell will break and the kernel will turn brown and reduce the quality of the product.
