• A small amount of process water is quickly circulated to quickly reach the predetermined sterilization temperature.
• Reduce steam consumption. Steam and atomized water are directly mixed in the retort sterilizer to increase the speed of temperature rise and reduction.
• Low noise, creating a quiet and comfortable working environment.
• The kettle is equipped with four movable temperature sensing probes, which can monitor the F value of the food center and the heat distribution in the kettle at any time to understand the heat penetration.
• Perfect pressure control, especially suitable for products containing gas packaging.
• An optional automatic door opening.
• Single-pot spray type (inter-rise and inter-cool) high temperature and high-pressure conditioning sterilization kettle.
• The full-function sterilization kettle is suitable for all kinds of high-temperature-resistant packaging materials.
• Suitable containers: glass bottle containers, tinplate cans, aluminum cans, PP bottles, HDPE bottles, aluminum foil bag, transparent bag, vacuum bag, high-temperature cooking bag, etc.
• Indirect heating and cooling: the cooling water and process water are not in contact, avoiding secondary pollution of food. Without using water treatment chemicals, sterilizer at high temperature for a short time.
• Sterilizing temperature and sterilizing time can be adjusted according to technological process requirements.
• The whole retort sterilizing system is made of food-grade SUS304 material.
• PLC touch screen automatic control, paperless recorder, with safety protection device, steam and water mixer heating, automatic temperature control and sterilizing temperature between 80-143 ℃ adjustable. Control parts are all adopted by famous brand like JUMO, SIEMENS, SCHNEIDER, and DANFOSS to keep high performance of the whole machine.

A full automatic retort sterilizer is composed of parts:

–Retort body: Including pot body, pot cover, crank arm, track, sealing ring, roller, locking iron block, steam pipe, spray pipe, and cooling pipe. the

–Control system: PLC controller, touch screen, control cabinet, electromagnetic reversing valve, temperature sensor, pressure sensor, proximity switch.

–Auxiliary system: pallets, pallet trucks, circulating pumps, water pumps, pipeline valves, thermometers, pressure gauges, etc.

–Cage/basket loading and unloading system: The basket loading system is for unloading the containers such as bottles, pouches and cans from conveyors to sterilization baskets and the baskets will be conveyed to the retort sterilizer for sterilizing; After the containers are finished sterilizing, the containers in sterilizing baskets will be loaded into the conveyors again for next station processing. The whole system is composed of a lifting system, lifting platform, multiple sterilization baskets, track rail, trolley, etc. It can also be divided into semi-automatic or full-automatic machines.

Working Process

Firstly the container will load into cages automatically, then after the basket is full, the basket will transfer to retort through the track, and the retort door will open automatically after detecting the food basket close to the door. Thirdly the retort will start sterilizing and after finished sterilizing,  the retort kettle door will be opened and the basket will be transferred out of the retort by track rail and loaded into the conveyor again.

—Heating Material: Stationary retort sterilizer for low-viscosity liquids such as milk, juice; Rotatory retort sterilizer for high viscosity products such as porridge.

—Structure Type:  Single layer spray type sterilizer and double layer water bath type sterilizer.

—Control Mode: Semi-automatic and fully automatic.

—Heating Source: Electronic heating and steam heating.

The use of retort sterilizer to sterilize food and beverage can effectively extend the shelf life of products, it is widely used to sterilize milk or juice, porridge, chicken and duck products, braised meat, pork trotters, dried beans, sausages, fruit jams, braised eggs, and other products.

• Canning of Fruits and Vegetables: Retort sterilization is commonly used for canning fruits and vegetables to eliminate bacteria, yeast, molds, and enzymes that can cause spoilage. This process helps extend the shelf life of canned fruits and vegetables.
• Beverages: Some beverage products, like ready-to-drink coffee, tea, and certain fruit juices, may undergo retort sterilization to ensure microbiological safety and extend shelf life.
• Sauces, Fruit Pulp and Condiments: Various sauces, including tomato sauce, salsa, and condiments, can be sterilized using retort sterilization to ensure the elimination of microorganisms and achieve product stability.
• Meat and Poultry Products: Processed meat and poultry products, such as canned soups, stews, and ready-to-eat meals, undergo retort sterilization to ensure the elimination of harmful microorganisms and achieve a long shelf life.
• Dairy Products: Certain dairy products, such as condensed milk and flavored milk, undergo retort sterilization to achieve a longer shelf life. This process helps in preserving the nutritional content of the products.
• Seafood Processing: Canned fish and seafood products, such as tuna and salmon, are often subjected to retort sterilization.

Suitable sterilization containers:

• Bottle containers: PP bottles, HDPE bottles, Glass bottles or glass jars.
• Soft bag packaging: tin foil bag, transparent bag, vacuum bag, high-temperature cooking bag, etc.
• Mental Cans: Tinplate cans and aluminum cans
