Description
Technical Field
The invention relates to a biological medicine stock solution freeze-thawing device, in particular to a contact type horizontal freeze-thawing box.
Background
The ultra-low temperature freezing and thawing shell is used for protecting the outer shell of the flexible bag in low temperature freezing and thawing and is an important component for the original liquid freezing and storing application in the biological pharmacy. The freeze-thaw box is generally rectangular in shape, and upper and lower plates thereof are generally made of metal for better heat transfer and freezing effects. CN212829972U, CN111776476A and the like disclose structures of some existing freezing and thawing boxes so as to solve the technical problem that the freezing and thawing substrate layer is adhered to the packaging bag to cause the packaging bag to be easily torn.
The rigid shell can not only protect the flexible freezing-thawing bag inside, but also can mould the shape, thickness and the like of the liquid after solidification and expansion during freezing. In order to ensure that the shape of the freezing-thawing box is not deformed during the freezing-thawing process, a certain space or elastomer is generally required to be arranged inside the freezing-thawing box to absorb liquid expansion. For example, CN109890716a absorbs the expansion during freezing by lining the foam inside the shell, making use of the elasticity of the foam. However, the elastic foam has poor heat transfer performance and certain water absorption, and due to the existence of micropores in the foam, dirt is easily absorbed, so that effective cleaning is difficult.
When the contact type horizontal freeze-thaw shell is contacted with the freezing plate of the freeze-thaw machine up and down and generates pressure, the upper surface and the lower surface of the freeze-thaw bag are firstly cooled and cured orderly, and the volume expands towards the peripheral direction due to the later cooling of the periphery and the central position. This results in a reduced height of the freezing and thawing bag, which prevents access to the upper surface of the freezing and thawing shell, and thus a reduced heat transfer efficiency. If the surrounding space is too small, the freezing and thawing bag is prevented from expanding all around, so that the freezing and thawing bag can only expand up and down easily, the upper surface and the lower surface of the freezing and thawing shell deform, and the result that the contact surface is uneven is caused.
The heights of contact type freeze-thaw shells on the market are fixed, once the height of an internal flexible freeze-thaw bag is reduced or increased, heat conduction is changed from metal plate contact type to air non-contact conduction, so that the freeze-thaw efficiency and the freeze-thaw uniformity are greatly reduced, and meanwhile, the protein in the biological medicine stock solution is subjected to enrichment reaction, and the protein activity is reduced.

The following disclosure provides many different embodiments, or examples, for implementing different aspects of the invention.
Referring to fig. 1 to 4, a contact type horizontal freeze thawing box comprises a main body frame 1, a lower bottom plate 2 and an upper cover 3, wherein the lower bottom plate 2 is matched with the main body frame 1,
at least one buffer plate 11 is arranged in the main body frame 1, the buffer plate 11 has elasticity, and a space capable of accommodating expansion during freeze thawing is formed between the buffer plate 11 and the inner wall of the main body frame 1; the main body frame 1 is provided with a positioning hole 12 and/or a positioning groove 12, the upper cover 3 is provided with a positioning block 31 matched with the positioning hole 12 and/or the positioning groove 12, and the positioning block 31 can slide in the positioning hole 12 and/or the positioning groove 12.
When the freezing and thawing device is used, the flexible freezing and thawing bag filled with liquid is placed in the box, the upper side and the lower side of the freezing and thawing bag are respectively contacted with the upper cover 3 and the lower bottom plate 2, the lower side surface of the freezing and thawing bag is directly contacted with the lower bottom plate 2 under the action of gravity, and the upper cover 3 has certain mass and is contacted with the upper surface of the freezing and thawing bag under the action of gravity. In the process of freezing and thawing, the liquid expands, and the positioning block is jacked up to provide a containing space for the expansion in the vertical direction. The expansion of the liquid in the box forms pressure on the buffer plate 11, and the buffer plate 11 deforms or is pushed to absorb corresponding expansion. In the whole freezing and thawing process, because the contact area between the upper cover 3 and the lower bottom plate 2 and the freezing and thawing bag is large, the heat transfer efficiency is better, more uniform cooling effect can be obtained, and the consistency of liquid freezing and thawing can be ensured.
The buffer plate 11 may be made of elastic plastic or metal, or other known materials. The elasticity can be from the material itself or from an elastic element cooperating therewith. The elastic element may be a spring or other common elastic element. The buffer plate 11 has no minute holes and thus is easy to clean.
When only one buffer plate 11 is used, it may be disposed in parallel to one side of the main body frame 1 to divide the inner space of the main body frame 1 into the accommodating space 4 of the flexible freezing and thawing bag and the space for absorbing expansion during freezing and thawing. Similarly, when 2 buffer plates 11 are used, 2 buffer plates can be arranged in parallel, or 2 buffer plates 11 can be arranged in perpendicular to each other, so as to form a flexible freeze-thaw bag containing space 4 and 2 spaces for absorbing expansion during freeze thawing. When in use, the expansion generated when the liquid in the flexible freeze-thaw bag is frozen can be better absorbed.
In some examples of contact type horizontal freeze/thaw boxes, a plurality of buffer plates 11 are provided in the main body frame 1. The uniformity in all directions is guaranteed. If necessary, the freeze-thaw bag accommodating space 4 with different shapes can be obtained by replacing and/or combining the buffer plates 11 with different shapes, and the freeze-thaw bags with different shapes can be matched.
In some examples of contact type horizontal freezing and thawing boxes, four buffer plates 11 are provided in the body frame 1, the four buffer plates 11 forming a space 4 for accommodating a flexible bag. Specifically, as shown in fig. 4, the front bumper plate 11 (with a notch) is combined with the other three bumper plates 11 by means of a snap-fit. The front buffer plate 11 and the rear buffer plate 11 are fixed on the inner side of the main body frame 1 through a clamping groove 14.

So that the buffer plates 11 at both sides can slide in the slide grooves. When the freezing and expanding liquid storage bag is used, the buffer plates 11 on the left side and the right side are better abutted against the two side surfaces of the flexible freezing and thawing bag under the action of the elastic pieces, and the buffer plates 11 move towards the left side and the right side of the main body frame 1 to absorb the expansion of the liquid under the pressure of the buffer plates 11 on the left side and the right side in the freezing and expanding process of the liquid.
In some examples of contact-type horizontal freezing and thawing boxes, the space between the buffer plate 11 and the main body frame 1 is provided with an elastic member. The elastic part enables the buffer plate 11 to be in more sufficient contact with the side surface of the freeze-thaw bag under the action of elasticity.
In order to obtain better heat transfer effect, the surfaces of the upper cover 3 and the lower base plate 2, which are in direct contact with the freeze-thawing bag, are made of metal materials, and the metal materials can be stainless steel and the like.
In some examples of contact type horizontal freeze-thaw boxes, the main body frame 1 is provided with a slide 13, and the lower plate 2 is engaged with the main body frame 1 through the slide 13. This facilitates assembly and also facilitates replacement of damaged components. Of course, the lower plate 2 may be directly fixed to the main body frame 1.
In some contact horizontal freeze-thaw cassettes examples, the main frame 1 and the upper lid 3 are provided with matching turrets 5. When not in use, the freezing and thawing box can be conveniently fixed into a whole.
