Problems solved by technology

[0003] Nowadays, in the process of freezing liquid intermediate products in pharmaceutical preparation operations, a plurality of reagent tubes are usually stored on the rack and the rack is stored in the freezer for freezing operations. In the prior art, the freezing operation is generally Refrigerate from the side wall of the box, and then cool down the middle position through heat exchange, so that the reagent freezing rate at each position on the actual shelf varies greatly, which affects the actual freezing effect of the reagent

Embodiment 1

[0027] refer to Figure 1-3 , a freezing device for preparation of medicaments, comprising a freezer 1, a storage box 2 is fixed inside the freezer 1, and a connection cavity 3 is provided between the outer wall of the storage box 2 and the inner wall of the freezer 1, and the connection cavity 3 Both the bottom and the bottom of the box are connected with connecting pipes 6, and it is characterized in that a plurality of placement seats 4 are slidably connected between the inner walls of both sides of the placement box 2, and the top of the placement seat 4 is provided with placement holes 5 distributed equidistantly. The position corresponding to the placement hole 5 on one side of the outer wall of the seat 4 is provided with a communication hole 7 that runs through it horizontally, and a perforation is provided at the position corresponding to the communication hole 7 on both sides of the placement box 2, and one end of the freezer 1 and the placement box 2 are provided. T...

Embodiment 2

[0035] refer to Figure 1-4 , a refrigerating device used for preparation of medicaments, support blocks 17 are fixed on both sides of the top and bottom ends between the outer wall of the storage box 2 and the inner wall of the freezer 1, and the outer wall of the support block 17 is rotatably connected with a connecting ring 18 The outer wall of the connection ring 18 is fixed with a plurality of guide vanes 19, and the flow dispersion effect of the cold air in the connection chamber 3 in the horizontal direction is increased through the top and bottom rotating guide vanes 19, thereby enhancing the uniformity and uniformity of the actual freezing. freezing effect;

[0036] The inner walls on both sides of the placement box 2 are fixed with a plurality of spacer frames 20 of C-shaped structure, and the placement seat 4 is slidably placed between the spacer frames 20. The through-groove is set through, and the inner wall of the through-groove is fixed with a heat-conducting s...

Embodiment 3

[0039] refer to Figure 1-4 , a freezing method for a freezing device used for preparation of medicaments, comprising a freezing box 1, a storage box 2, a connecting chamber 3, a connecting pipe 6, a placing seat 4, a placing hole 5, a communicating hole 7, a connecting hole 8, and a middle hole 9 and auxiliary hole 10, the reagent tube is inserted and placed in the placement hole 5 on the placement seat 4, and the cold air is circulated in the connection cavity 3 through the connecting pipe 6 to carry out the freezing operation in the placement box 2, and the device makes the placement seat 4 The communication hole 7 in the middle position communicates with a plurality of placement holes 5 and the through hole communicates with the connection cavity 3, so that the cold air can be quickly distributed along the perforation hole, the communication hole 7, the connection hole 8, the middle hole 9 and the auxiliary hole 10 in the same Place in the placement holes 5 at various posi...

Abstract

The invention discloses a freezing device and a freezing method for medicament preparation. The device comprises a freezing box, wherein a placing box is fixed in the freezing box; a connecting cavityis formed between the outer wall of the placing box and the inner wall of the freezing box; the bottom of the connecting cavity and the bottom of the freezing box are connected with connecting pipes;a plurality of placing seats are connected between the inner walls of the two sides of the placing box in a sliding mode; placing holes which are distributed at equal intervals are formed in the topsof the placing seats; and communicating holes which are horizontally arranged in a penetrating mode are formed in the positions, corresponding to the placing holes, of the outer walls of one sides ofthe placing seats. According to the method, cold air is rapidly distributed in the placing holes in all positions of the same placing seat along the penetrating holes, the communicating holes and theplacing holes, so that the freezing rate difference of reagents at all positions is reduced, and as a result, the actual freezing effect is improved. According to the device and the method, the coldair cooled at the openings of the side communicating holes is uniformly dispersed to the reagent positions at all positions, so that the freezing rate difference of the reagents is further reduced.

Description

technical field [0001] The invention relates to the technical field of medicament preparation, in particular to a freezing device and a freezing method for medicament preparation. Background technique [0002] Pharmaceutical preparations are the combination of raw materials and various auxiliary materials such as adhesives, antioxidants, excipients, flavoring agents, etc., to make corresponding dosage forms. Simple ones include tablets, capsules, and injections, and more complicated ones include Sustained and controlled release, microsphere pellets, eye drops, tincture, etc., according to actual needs, choose different processes to process and process different raw materials into required pharmaceutical preparations. In fact, in the process of pharmaceutical preparation, it is often necessary to liquidate the intermediate product The ingredients are frozen before further processing. [0003] Nowadays, in the process of freezing liquid intermediate products in pharmaceutical...
