Sides Spray Retort

Side spray retort is a great fit for flexible pouches, especially heat-sensitive products. A heat exchanger is applied for heating and cooling, which prevents products from being contaminated by steam and cooling water. This also eliminates the need for adding water treatment chemicals (like chlorine). The process water is drawn by a water pump, and sprayed evenly onto the products through the spray nozzles located at the four corners of each retort tray, thus achieving the goal of sterilization while ensuring temperature uniformity during the heating and cooling processes.

Features

Accurate temperature control, excellent heat distribution: The temperature control module developed by DTS allows for up to 12 stages of temperature control. The heating mode is available in step or linearity to accommodate the specific formulations of different products. Thus, the repeatability and stability between batches of products are well ensured, with a temperature accuracy within ±0.5℃.

Precise pressure control, suitable for different package types: The pressure control module developed by DTS continuously changes the pressure during the entire process to adapt to the pressure variations inside the package. This minimizes the deformation of the package, no matter it is plastic bottles/boxes, or flexible pouches. The pressure accuracy is within ±0.05bar.

Highly clean product package: Heat exchanger is applied for indirect heating and cooling, thus avoiding secondary contamination caused by the steam and cooling water since they do not come into contact with the process water. Besides, water treatment chemicals such as chlorine are no longer required, and the service life of the heat exchanger can also be considerably extended.

Energy saving and eco-friendly: A small amount of process water is used for circulation, enabling the sterilizing temperature to be reached quickly.
Low noise offers a silent and comfortable working environment.
In contrast to direct steam sterilization, there is no need for removing air from the retort prior to heating, resulting in significant steam savings of 30%.

In compliance with FDA/USDA certificate: Backed by its team of seasoned thermal processing specialists, DTS has become a member of IFTPS and works in full cooperation with FDA-recognized third-party accreditation bodies. Years of experience in working with many North American customers means we understand the regulatory requirements of FDA/USDA and state-of-the-art sterilization technology.

How It Works

First, inject process water into the resort. The water can be pre-heated for sterilizing hot-filling products.

Next, switch on the high-flow pump and four-directional spray nozzles on each product tray. The result is that all products, regardless of their position in the tray, top or bottom layer, front or back, receive the same level of sterilization. This is achieved by ensuring that the heating and sterilization quality are ideal. The precise and accurate nozzle direction allows for even hot water diffusion at the center of each tray, which minimizes uneven temperature distribution within the large sterilizer’s processing tank.

The tubular heat exchanger in the retort allows the process water to flow in one side, and the steam in the other, so that germ-free sterilization can be achieved as the product won’t come directly into contact with the steam. The pressure inside the sterilization retort is set by program-controlled automatic valves that allow compressed air flowing into or out of the resort. Since the technique adopted is water spray, the pressure can be freely adjusted according to the package of sterilized product, and will not be affected by temperature. This would make the sterilization equipment more widely applicable in three-piece cans, two-piece cans, flexible packaging bags, glass bottles, plastic packaging, etc.

Finally, wait for the alarm signal for completing the sterilization. And the door can then be opened and the product can be unloaded, after which the equipment is ready to sterilize the next batch of products.

The temperature distribution inside the retort has a uniformity of +/- 0.5℃. The pressure is controlled at 0.05 bar.
