100L vertical autoclave small scale autoclave for canned food

small scale autoclave description

canned food, especially canned meat need to be fully sterilized in order to get an extended shelf life udner ambient temperature. In order to get the canned food fully sterilized, we need to use autoclave, or retort. we also call it as sterilizer retort, or retort sterilizer. or autocalve sterilizer. You can finish the sterilization process in an autoclave. 

Ranking machinery offer autoclave or retort with both small scale and large scale. the smallest autoclave can be 60Liter and the biggest autoclave can be 6000Liter or more. For smale scale autoclave, most of our users choose electric heating medium. Electric heating autoclave / retort comes with a group of interior heating elements which immersed in water during sterilization process. When sterilization, heating elements will turn water into steam and an exterior water circulation pump will circulate hot water from retort chamber bottom to the top side and spray onto the canned food to be sterilized.

for automatic contrl autoclave, there will be prerssure sensor on the retort chamber. working pressure can be read on the control touch screen or LCD screen as well.  

compressed air inlet valve

electric heating type autoclave belongs to back pressure autoclave. there is a pipe for comressed air inlet. 

manual control type autoclave reqeust operators control the working prerssure by hand. 

automatic control type autoclave / retort will control the sterilization pressure buy programe. 

electric heating autoclave temperature & pressure control

small scale vertical autocalve can be semi-manual control type or automatic control type. with semi automatc control system, you preset the sterilization temperature and holding time into the temperature gauge and timer, start the heating manually, then system will control the temperature and time automatically. during the sterilization process, you will need to control the pressure manually.the cooling process is also finished manually.

automatic control type autoclave will control temperature, pressure, sterilization time, cooling temperature all by programe. user's do not need to watch the sterilization process after the figures was preset into the automatic control system. 

autoimatic control autoclave use Simense  touch screen or other local brand touch screen or button type LCD. 

date logger or papper less recorder is optional.

1.  After the sterilization process of your back prerssureautocalve / retrot, will the canned food get a long shelf life?

2. What is the best sterilization temperature for our vacuum packed beans and bottles food?

Fod different product and package, the sterilization temperature may be different. user's will need to find out the most suitable sterilization temperature. Temperatures of 110°C will kill most Bacillus spores1 within a short time. In the case of Clostridium temperatures of up to 121°C are needed to kill the spores within a relatively short time. Ranking Machiner can help you to find out the most suitable sterilization temperature and sterilization time as well as the sterilization pressure within a few sterilization cycles.

3. What is the sterilization process for canned fish?

The sterilization process in the canned product can be subdivided into three phases see this picture below please. By means of a heating medium (Hot water or steam) the canned food temperature is increased from ambient to the required sterilization temperature (phase 1 = heating phase). This temperature is maintained for a defined time (phase 2 = holding phasing or sterilization phase). In (phase 3 = cooling phase) the temperature in the can is decreased by  introduction of cold water into the autoclave / retort sterilizer.

6. for meant and beans in glass jar / glass bottle, what kind of autoclave do you suggest?

accoreding to our years of experiance in autoclave production, and based on our user's feedback in the past decades, the most suitable autoclave for mean in tin can and glass jar or glass bottles will be a double vessel autoclave water immersion type or with rotary system.

Horizontal autoclaves / horizontal retort sterilizer can be built as single or double vessel system. Ranking Machinery whatsapp +8618072138651 , Email- tcmachine(at)outlook.com.The double vessel systems have the advantage that the water is heated up in the upper vessel to the sterilization temperature and released into the lower (processing) vessel, when it is loaded and hermetically closed. Using the two–vessel system, the heat treatment can begin immediately without lengthy heating up of the processing vessel and the hot water can be recycled afterwards for immediate use in the following sterilization cycle.

rotary type autoclave / retort

rotary type autoclave suitable for meant and beans in glass jar, tin can, vacuum package, doypack, as well as glass bottles. With the rotary system, all the goodds will turn over and over in the autoclave chamber during the sterilization process which lead to a high cooking effiency and cooling phasw will also much more fast. Rotary type autoclave mainly used to the sterilization of thick product or canned / bottles product.
