A kind of wolfberry drying production line

Abstract

The invention relates to the technical field of traditional Chinese medicinal material processing and discloses a wolfberry drying production line. The wolfberry drying production line comprises a laser perforating machine and a vacuum microwave drying device. Wolfberries are transferred between the laser perforating machine and the vacuum microwave drying device through a material basket. According to the wolfberry drying production line, as for characteristics of the wolfberries, the laser perforating machine is used for perforating the wolfberries, and fruit wax on the surface of the fresh wolfberries is removed; then the vacuum microwave drying device is used for vacuum drying of the perforated wolfberries, the drying efficiency is high, the drying time is short, influences on the appearance of the fresh wolfberries are small, drying is uniform, the dried wolfberries are bright in color and lustre and not prone to absorbing moisture and hardening, and the drying quality of the wolfberries is improved.

Description

technical field [0001] The invention relates to the technical field of processing Chinese medicinal materials, in particular to a wolfberry drying production line. Background technique [0002] Fresh fruits such as wolfberry have high water content and thin skin, which are easy to damage, mildew, and are not resistant to storage. They are generally sold as dry products. However, the epidermis of goji berries is protected by a waxy layer, and the sugar content inside is high, so direct drying or drying after picking will bring certain problems: the protection of the waxy layer makes it difficult for the inner moisture of goji berries to evaporate, which will easily lead to browning. If the temperature is slightly higher, the sugar inside the wolfberry will seep out, resulting in sticking, hardening and loss of nutrients. Therefore, it is necessary to remove the fruit wax of wolfberry and other fresh fruits, and then take them to dry. In the prior art, the fresh wolfberry fr...

Problems solved by technology

However, the epidermis of goji berries is protected by a waxy layer, and the sugar content inside is high, so direct drying or drying after picking will bring certain problems: the protection of the waxy layer makes it difficult for the inner moisture of goji berries to evaporate, which will easily lead to browning. mildew; a slightly higher temperature will cause the sugar inside the wolfberry to ooze out, resulting in sticking, hardening and loss of nutrients

In the prior art, the fresh wolfberry fruit uses sodium hydroxide to break the fruit wax, and then sodium sulfite to protect the color, but the use of sodium hydroxide to break the fruit wax has the following problems: one is to affect the taste; the other is not green, and there are certain problems in food safety; the third is large After part of the fruit wax is removed, it is easy to cause the dried goji berries to absorb moisture and stick together, and the existing drying technology generally uses air drying or oven drying, which has low drying efficiency and uneven drying. Goji berries are prone to browning during the drying process, which affects the quality of goji berries.
