Double screw freezer

 With the rapid development of the food industry and the continuous innovation of food machinery, a new type of high-efficiency, energy-saving quick-freezing device with compact structure and small floor space-DLD, SLD series spiral quick-freezing devices has become a large and medium-sized quick-freezing food company Choice of models.

        The stainless steel material conveying mesh belt of the DLD, SLD series spiral quick freezing device rotates spirally in the freezing chamber, so as to achieve rapid freezing of the material. The top and side air blowing methods are adopted respectively, and the freezing time can be selected from 20 to 90 minutes. It is suitable for fast freezing of prepared food, small package food, split meat, ice cream, etc. It can also be used for seafood, fruits, and quick frozen frozen vegetable products.

>> SLD Series Double Spiral Quick Freezing Features

   In order to meet the market demand, our company has developed a new type of double spiral quick freezing device based on the single spiral quick freezing device. It adopts the structure of two turrets. In addition to the characteristics of the single spiral quick freezing machine, it also has the following features: Features:

    ◆ Large freezing capacity: Due to the double turret spiral structure, the characteristics of the spiral quick-freezer are more fully utilized, so the double spiral structure is particularly suitable for large-scale quick-frozen food enterprises.

     ◆ The structure design is more suitable for modern production: the inlet and outlet of the single-screw quick-freezing device can only be divided into two types: top-in, bottom-out, or bottom-in, top-out. The double-spiral inlet and outlet are below, and the inlet and outlet directions. The choice is also more flexible, and it is easier to combine with other supporting equipment to achieve modern assembly line production.

     ◆ Wider and more flexible for frozen products: Because the two spiral structure design can be carried out separately, the pre-cooling process and equipment can be omitted for cooked food quick-freezing production enterprises, so that the pre-cooling and quick-freezing process can be completed at one time. Suitable for quick-freezing lumps.
