The key aspects to consider before choosing your autoclave for canning

The sterilization of canned food is a preservation technique where food is subjected to high temperatures for a certain period of time to destroy all microorganisms that inhabit it, both pathogens (those that can cause human disease) and non-pathogens.

The purpose of sterilization of food packed in hermetic containers is the destruction of all bacteria, including their spores, without significantly altering the organoleptic and nutritional characteristics of the original food product, making the food safe for human consumption and at the same time extending its shelf life.

Types of autoclave for canning

Domestic canning with pressure cookers

We can make preserves at home using bain-marie or a pressure canner, but in order to make them safe for later human consumption it is advisable to follow a series of steps rigorously.

Glass jars are the most appropriate container for making home preserves, they must be previously washed in the dishwasher at high temperature, dried completely and filled with food while still hot to avoid thermal shock and leaving a small free space at the top to allow adequate expansion of the product during sterilization.

Then, without leaving bubbles and without dirtying the rim of the jars, they should be closed and placed in a pot with enough water to cover them and bring them to boiling for a minimum of 12 minutes, depending on the specific product used. It is advisable to use a rack to avoid direct contact of the jars with the bottom of the equipment. After the boiling time, it is advisable to wait about 5 or 10 minutes to remove them from the pot and they should be allowed to cool to room temperature while maintaining their vertical position for 8 to 12 hours and they will be ready for consumption at home.

There is also a wide variety of large-capacity household sterilizers or electric pots on the market, from 1 to 20 liters, with various functions and multiple accessories. With these equipments you will be able to prepare homemade preserves by manually programming the time and temperature.

Automatic autoclaves for canning

On the other hand, if what you want to do is make preserves in a traditional way with the ability to market them you should definitely use a professional automatic autoclave for canning.

Professional food autoclaves or canning sterilizers are hermetic equipment created to sterilize food packed in glass, metal or semi-rigid containers by subjecting them to high pressure and at temperatures above 100ºC for a certain time.

To guarantee food safety and compliance with health and hygiene regulations, artisan preserves producers must have an autoclave.

Industrial autoclaves for canning

For large productions, there are autoclaves for food and ready meals adapted for industrial processes. Of modular constructions and adaptable to the volume and capacity of each production, industrial autoclaves are very large and work with mixture of steam, water and air. They can be programmed according to the required process and can reach up to 140ºC.

Autoclaves for canning for small artisan producers

Dedicating yourself to canning in a professional way means giving up certain habits typical of manual work. Producing a preserve to be sold to third parties requires rigor.

Gone is the cumbersome task of boiling the containers to be used, at least for 15 minutes, and their subsequent drying. We must also forget about cooking the jars in a pot (face up or face down) filled, closed and covered with water. Always waiting and with crossed fingers so that every pot has been properly vacuum sealed.

When we turn canning into our business, we can no longer afford all this, we cannot trust in luck that our jars are in perfect safe conditions. Clearly, it would be fatal for our company if our products were not in optimal conditions. Quality and food safety must be a priority.
