The invention relates to the technical field of freeze-
drying equipment, in particular to a pericarp tea vacuum freeze-
drying device with an enzymolysis
temperature control module and a process, the pericarp tea vacuum freeze-
drying device comprises a heater, a motor, a freeze dryer and a
nitrogen making
machine which are installed in a
machine shell, a pair of storage devices is arranged on the top face of the
machine shell in a sliding mode, and the storage devices are filled with
nitrogen after freeze-drying; the storage device comprises a storage box, a box cover set used for adjusting the internal space arrangement of the storage box and a cover locking ring. According to the invention, the integrated box cover group with switchable functions is arranged, so that the integrated operation of stirring enzymolysis and partitioned
nitrogen charging is completed; in the enzymolysis stage, a stirring column is inserted for mechanical stirring, so that peels are in full contact with
enzyme liquid, and the uniformity and efficiency of
fiber degradation are remarkably improved; in the freeze-drying nitrogen charging stage, the gas distribution plate is switched to be inserted, the material bin is divided into a plurality of independent gas channels, uniform replacement of material pores in a nitrogen partition and concentration mode is achieved, the
oxygen residual quantity is greatly reduced, and active ingredients are reserved.
