Problems solved by technology

This kind of freeze dryer has the following disadvantages: 1. The freeze-drying box and the cold trap are connected through a connecting pipe, and the connecting pipe needs to open a large hole on the freeze-drying box and the cold trap, and install it with a large flange. The valve leads to complex structure, high cost, and difficult manufacturing and assembly. The driving cylinder of the on-off valve will also cause pollution to the product; 2. The freeze-drying box and the cold trap are two independent containers arranged horizontally side by side, and the manufacturing cost is high. , Take up a lot of space, and it is inconvenient to assemble and transport

Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] Such as figure 1 As shown, the lyophilizer of the present invention includes a freeze-drying chamber 1 and a cold trap chamber 5, and a coil 8 for refrigeration is provided in the cold-trap chamber 5; Above the multiple freeze-dried slabs 3, the top of the freeze-dried chamber 1 is provided with a lifting drive 4 for driving the support plate 2 and the freeze-dried slabs 3 up and down. The lifting drive 4 in this embodiment is an oil cylinder. During work, after the bottle body in a half-stoppered state completes freeze-drying on the freeze-drying plate layer 3, the support plate 2 and each freeze-drying plate layer 3 will move down under the drive of the lifting drive member 4, so that each freeze-drying plate layer The layers 3 are close to each other for plugging, and the rubber stopper on the bottle body is completely pres...

Abstract

The invention discloses a freeze dryer. The freeze dryer comprises a freeze-drying cavity and a cold-trap cavity. A supporting plate and a plurality of freeze-drying plate layers arranged above the supporting plate are arranged in the freeze-drying cavity, a lifting and dropping driving piece used for driving the supporting plate and the freeze-drying plate layers to lift and drop is arranged on the freeze-drying cavity, the freeze-drying cavity is arranged above the cold-trap cavity, the freeze-drying cavity is communicated with the cold-trap cavity through a through hole formed in the bottom of the freeze-drying cavity, and the supporting plate covers the through hole when the supporting plate drops to the bottom of the freeze-drying cavity so that the freeze-drying cavity can be separated from the cold-trap cavity. The freeze dryer has the advantages of being simple in structure, low in cost, small in occupied space, low in pollution risk and the like.

Description

technical field [0001] The invention mainly relates to the field of food and medicine packaging machinery, in particular to a freeze dryer. Background technique [0002] In the field of food and pharmaceutical packaging machinery, the freeze-drying box and the cold trap of the traditional freeze-dryer generally adopt a split structure and are arranged side by side horizontally, that is, the freeze-drying box and the cold trap are two independent containers. It is connected through a pipe and has an independent on-off valve. This kind of freeze dryer has the following disadvantages: 1. The freeze-drying box and the cold trap are connected through a connecting pipe, and the connecting pipe needs to open a large hole on the freeze-drying box and the cold trap, and install it with a large flange. The valve leads to complex structure, high cost, and difficult manufacturing and assembly. The driving cylinder of the on-off valve will also cause pollution to the product; 2. The fre...
