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 pharmaceutical preparation, comprising a freezing box 1, a placing box 2 is fixed inside the freezing box 1, and a connecting cavity 3 is provided between the outer wall of the placing box 2 and the inner wall of the freezing box 1, and the connecting cavity 3 The bottom and the bottom of the container are connected with connecting pipes 6, and it is characterized in that a plurality of placement seats 4 are slidably connected between the two inner walls of the placement box 2, and the top of the placement seats 4 is provided with placement holes 5 distributed at equal distances. The position corresponding to the outer wall of one side of the seat 4 and the placement hole 5 is provided with a communication hole 7 arranged horizontally through, and the positions corresponding to the communication hole 7 on both sides of the placement box 2 are provided with perforations, and one end of the freezer box 1 and the placement box 2 ...

Embodiment 2

[0035] refer to Figure 1-4 , a freezing device for pharmaceutical preparation, the top and bottom sides between the outer wall of the placing box 2 and the inner wall of the freezing box 1 are fixed with a support block 17, and the outer wall of the support block 17 is rotatably connected with a connecting ring 18 through a bearing , the outer wall of the connecting ring 18 is fixed with a plurality of guide vanes 19, and the guide vanes 19 rotating at the top and the bottom increase the flow and dispersion effect of the cold air in the connecting cavity 3 in the horizontal direction, thereby enhancing the actual freezing uniformity and efficiency. freezing effect;

[0036] A plurality of limit frames 20 with C-shaped structures are fixed on both inner walls of the placing box 2 , and the placing seat 4 is slidably placed between the limit frames 20 . The position corresponding to the limit frame 20 and the placing box 2 is provided with The penetrating groove is provided, a...

Embodiment 3

[0039] refer to Figure 1-4 , a freezing method for a freezing device for pharmaceutical preparation, comprising a freezing box 1, a placing box 2, a connecting cavity 3, a connecting pipe 6, a placing seat 4, a placing hole 5, a communication hole 7, a connecting hole 8, a middle hole 9 and the auxiliary hole 10, insert the reagent tube into the placing hole 5 on the placing seat 4, and circulate the cold air in the connecting cavity 3 through the connecting pipe 6 to perform the freezing operation in the placing box 2, and the device makes the placing seat 4. The communication hole 7 and the perforation communicated with the plurality of placement holes 5 in the middle position are communicated with the connecting cavity 3, so that the cold air is quickly distributed along the perforation, the communication hole 7, the connecting hole 8, the middle hole 9 and the auxiliary hole 10 in the same one. In the placement hole 5 of each position on the placement seat 4, in order to ...

Abstract

The invention discloses a freezing device and a freezing method for pharmaceutical preparation. The device comprises a freezing box, a placing box is fixed inside the freezing box, and a connecting cavity is provided between the outer wall of the placing box and the inner wall of the freezing box , the bottom and bottom of the connection cavity are connected with connecting pipes, a plurality of placement seats are slidably connected between the two inner walls of the placement box, and the top of the placement seats is provided with placement holes distributed at equal distances. The position corresponding to the side outer wall and the placement hole is provided with a communication hole arranged horizontally through; the method enables the cold air to be quickly distributed in the placement hole of each position on the same placement seat along the perforation, the communication hole and the placement hole, so as to reduce the size of each position The freezing rate of the reagents varies, thereby increasing the actual freezing effect. The invention makes the cold air cooled at the opening of the side communication hole evenly dispersed to the reagent positions at various positions, and further reduces the difference in the freezing rate of the reagents.

Description

technical field [0001] The present 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 excipients such as adhesives, antioxidants, excipients, and flavoring agents to make corresponding dosage forms. Sustained and controlled release, microspheres and pellets, eye drops, tinctures, etc., according to actual needs, different processes are selected to process and process different raw materials into the required pharmaceutical preparations. The ingredients are frozen for subsequent processing. [0003] Nowadays, in the process of freezing liquid intermediates in pharmaceutical preparation operations, a plurality of reagent tubes are generally stored on the placing rack, and the placing rack is stored in the freezing box for freezing operation. In the prior art, the freezin...
