Steam& Air Retort

Short Description:

By adding a fan on the basis of steam sterilization, the heating medium and the packaged food are in direct contact and forced convection, and the presence of air in the sterilizer is allowed. The pressure can be controlled independently of the temperature. The sterilizer can set multiple stages according to different products of different packages.

Accurate temperature control, excellent heat distribution

The temperature control module (**** system) developed by DTS has up to 12 stages of temperature control, and the step or linearity can be selected according to different product and process recipe heating modes, so that the repeatability and stability between batches of products are maximized well, the temperature can be controlled within ±0.3℃.

No need to heat other media (such as hot water), the heating rate is very fast.

Perfect pressure control, suitable for a variety of packaging forms

The pressure control module (**** system) developed by DTS continuously adjusts the pressure throughout the whole process to adapt the internal pressure changes of the product packaging, so that the degree of deformation of the product packaging is minimized, regardless of the rigid container of tin cans, aluminum cans or plastic bottles, plastic boxes or flexible containers can be easily satisfied, and the pressure can be controlled within ±0.05Bar.

Compliant with FDA/USDA certificate

DTS has experienced thermal verification experts and is a member of IFTPS in the United States. It fully cooperates with FDA-approved third-party thermal verification agencies. The experience of many North American customers has made DTS familiar with FDA/USDA regulatory requirements and cutting-edge sterilization technology.

Energy saving and environmental protection

> The steam is directly heated, no exhaust is needed, and the minimum steam loss.

>Low noise, create a quiet and comfortable working environment.

Working principle

Put the product into the sterilization retort and close the door. The retort door is secured by triple safety interlocking. Throughout the whole process, the door is mechanically locked.

The sterilization process is automatically carried out according to the recipe input to the micro-processing controller PLC.

This system is based on the direct heating for food packaging by steam, without other heating media (for example, the spray system is used water as an intermediate medium). Since the powerful fan forces the steam in the retort to form a cycle, the steam is uniform. Fans can accelerate the heat exchange between steam and food packaging.

Throughout the whole process, the pressure inside the retort is controlled by the program by feeding or discharging compressed air through the automatic valve to the retort. Due to steam and air mixed sterilization, the pressure in the retort is not affected by temperature, and the pressure can be set freely according to the packaging of different products, making the equipment more widely applicable (three-piece cans, two-piece cans, flexible packaging bags, glass bottles, plastic packaging etc.).

The uniformity of temperature distribution in the retort is +/-0.3℃, and the pressure is controlled at 0.05Bar.
