Automatic production line of freeze-dried products

Abstract

The invention discloses an automatic production line of freeze-dried products. The automatic production line comprises a control system, a sterile isolator, a conveying mesh belt, a bottle washing system, a filling system, a freeze-drying system and a capping system, wherein the bottle washing system, the filling system, the freeze-drying system and the capping system are sequentially arranged inthe conveying direction of the conveying mesh belt, the conveying mesh belt, the filling system, the freeze-drying system and the capping system are all arranged in the sterile isolator, the conveyingmesh belt comprises a feeding transportation assembly and a discharging transportation assembly, the freeze-drying system comprises a freeze-drying cabinet, a feed front push device and a discharge rear push device, and the control system is correspondingly connected with the sterile isolator, the bottle washing system, the filling system, the freeze-drying system, the capping system and the conveying mesh belt. According to the automatic production line of the freeze-dried products, the aseptic requirement is met, automatic feeding and discharging of the freeze-drying cabinet can be realizedcontinuously and stably, feeding and discharging of the freeze-dried products are independent, discharging can be carried out while feeding is carried out, the structure is simple, and use is convenient.

Description

technical field [0001] The invention relates to the technical field of freeze dryers, in particular to an automatic production line for freeze-dried products. Background technique [0002] Freeze-drying production refers to freezing the drug into a solid state at a lower temperature, and then directly sublimating it into a gaseous state without going through the liquid state in a vacuum state, and finally dehydrating and drying the drug. The existing freeze-drying production line includes a filling and capping machine, a capping machine and a freeze-drying machine. After being filled and semi-stoppered by the filling and stoppering machine, the medicine enters the freeze-drying machine for freeze-drying, and the freeze-dried medicine is transported to the capping machine for rolling. Cover completes production. [0003] The automatic feeding and discharging methods of the freeze dryer in the existing production line are as follows: 1. Feeding: the semi-stoppered vials are f...

AI Technical Summary

Problems solved by technology

From the perspective of bottle transfer speed, the feeding and discharging device can basically meet the requirements for single-line and single freeze-dryer equipment, but for the whole line of multiple freeze-dryers, there are the following deficiencies in the process of use: due to the need to share the bottle body to transport Track, the feed of the freeze dryer at the downstream end affects the discharge of the freeze dryer at the upstream end, and the discharge of the upstream end affects the feed of the downstream end, so there are conflicts in demand between multiple freeze dryers; and between systems The control of the freeze-drying unit is complicated, and when a certain system fails, it is easy to affect the feeding and discharging operation of the whole line (the larger the freeze-drying unit, the easier it is to be affected)

[0005] In the above-mentioned prior art, because of the height difference H between the bottle conveying surface of the feeding transport component and the discharging transport component, it is necessary to add a docking robot, but the structure of the docking robot is relatively complicated, and the space occupied by the freeze-dried product production line is inherently small. It is extremely inconvenient to add complex and large mechanisms in a small space

In addition, the more components installed in the freeze-drying line, the more complicated the sterilization and cleaning of the freeze-drying line
