Problems solved by technology

[0008] For this reason, the first technical problem to be solved by the present invention is that the steam sterilization device in the prior art uses a jacket outside the sterilization chamber to preheat the sterilization chamber before sterilization, which is easy to The instant contact between the steam and the normal temperature tank will produce condensed water, which will lead to uneven and incomplete preheating of the sterilization chamber, making the temperature in the local area of ​​the chamber low; then after the high temperature steam enters the chamber, it will be due to The local low temperature causes the temperature to drop and condense, so that the raw material is soaked and damp after entering the cavity, so as to provide a uniform and sufficient preheating treatment for the device before sterilization, and the raw material enters the sterilization environment. A steam sterilizer that does not affect the properties of the product after sterilization due to moisture

Embodiment 1

[0046] figure 1 A schematic diagram of the steam sterilizing device according to the present invention is provided, and it can be seen from the figure that the steam sterilizing device includes a sterilization chamber 6 and a cooling chamber 15; The feed inlet 51 and the sterilization chamber outlet 52 are also provided with a rotary agitator 7 inside, the drive of the rotary agitator 7 can be selected to use any power source, and the electric motor 12 is selected for driving in this embodiment; Through the rotation and agitation of the blades on the rotary agitator 7, the material to be sterilized is continuously stirred and lifted up during the sterilization process; a hot air inlet 36 is also provided on the sterilization chamber 6, and the hot air enters The tuyere 36 is provided with a first branch air inlet 38 and a second branch air inlet 37, the first branch air inlet 38 is connected with the first hot air induced draft fan 1 through a pneumatic valve 32, and the secon...

Embodiment 2

[0052] The steam sterilizer described in this embodiment is as image 3 As shown, it is provided with a sterilization chamber shell 5 that forms an interlayer with the sterilization chamber 6 on the sterilization chamber 6, and fills the insulation medium in the interlayer, thereby reducing the process of the sterilization chamber at high temperature as much as possible. Neutralize the external energy exchange, thereby reducing the loss of high temperature and reducing energy consumption. Moreover, a feed hopper 9 is further provided at the feed port 51 of the sterilization chamber, and the feed hopper 9 and the feed port 51 of the sterilization chamber are connected through a pneumatic valve 8 at the feed port, thereby facilitating the addition of materials. Similarly, a discharge port pneumatic valve 26 can also be set between the sterilization bin discharge port 52 and the cooling bin feed port 53 to control the sterilized material to be transferred from the sterilization b...

Embodiment 3

[0059] Figure 4 Another embodiment of a steam sterilizer is shown.

[0060] Compared with the steam sterilizing device in Example 2, in the steam sterilizing device described in this embodiment, the setting of the filter screen 11 can not only correspond to the gas discharge port 33 inside the sterilization chamber 6 In order to avoid the dense dispersion of materials at the position of the sterilization chamber 6 when the airflow flows out from the gas discharge port 33, in this embodiment, at the position of the gas discharge port 33, along the A circle of filter screen 11 is set inside the bin 6, so that the materials carried in the airflow discharged through the gas discharge port 33 or the materials that may be attached to the inner wall of the sterilization bin 6 during the stirring and sterilization process may flow with the airflow. The material is collected on the filter screen 11 as much as possible to reduce its loss. In order to better realize the recovery of th...

Abstract

The invention discloses a steam sterilizing device, which comprises a sterilizing chamber and a cooling chamber. The sterilizing chamber and the cooling chamber are provided with a sterilizing chamber feeding hole, a sterilizing chamber discharge hole, a cooling chamber feeding hole and a cooling chamber discharge hole respectively; the cooling chamber feeding hole is connected with the sterilizing chamber discharge hole; a rotary stirrer is arranged in the sterilizing chamber; the sterilizing chamber is provided with a gas discharge port; and the sterilizing chamber is provided with a hot air inlet which is provided with a first branch air inlet and a second branch air inlet, wherein the first branch air inlet is connected with a first hot air draught fan through a pneumatic valve, and the second branch air inlet is connected with a second hot air draught fan and a steam generator through a storage steam heat exchanger respectively. The steam sterilizing device solves the problem that the steam sterilizing device in the prior art is not preheated or not preheated thoroughly to produce condensed water easily, and is particularly suitable for Chinese medicinal raw materials, food, flavoring and other raw materials.

Description

technical field [0001] The invention relates to a sterilizing device, in particular to a steam sterilizing device used in the fields of traditional Chinese medicine raw materials, food seasonings and other similar raw materials. Background technique [0002] Sterilization technology belongs to the basic technology of microbiology, which uses physical and chemical means to kill or remove the vegetative cells and their spores (or spores) of all microorganisms in the culture medium, fermentation equipment or other targets, so as to achieve the purpose of sterility. Sterilization technology is a necessary condition for culture medium, fermentation equipment or other target substances to obtain pure culture, and it is an indispensable technology to ensure food and drug safety in the food industry and pharmaceutical fields (especially in the field of traditional Chinese medicine production). [0003] The thoroughness of the sterilization technique depends on the two parameters of ...
