Scope of use of digesters:
Cooking boilers or as they are called syrup boilers are universal equipment that is used in the production lines of shops in various food industries, such as dairy, oil and fat, meat, fish processing and confectionery. It is also used in the field of catering for cooking such products as: jams, fruit gels, confectionery creams and fillings, preserves, syrups, ketchups, sauces, purees, pates and pastes from vegetables and fruits, mayonnaises, marinades, meat and vegetable broths, as well as for making fish and meat rolls, etc.
The jacketed mixer food cooker can also be used in industries such as cosmetics, perfumes, pharmaceuticals, paints and chemicals. They are intended for the manufacture of various types of products such as: ointments, creams, shampoos, tonics, lotions, hair dyes, balms, herbal syrups, medicines, as well as for the preparation of adhesives, various mixtures and fuels and lubricants.
The use of cooking kettles in various industries, their design features, material of manufacture, working volume, as well as equipment with various functionalities will depend on many factors, including the physical and mechanical characteristics of the raw material, the specifics of its preparation, as well as other important requirements, including the requirements of the Client .
Designs of digesters and their features
Vacuum cooking kettle is a 2 or 3-layer vacuum or atmospheric, upright or horizontal vessel, which is made of stainless or high carbon food grade steel, mounted on a solid metal frame or on support structures with regulators. Such a boiler can be equipped with a system for tilting the digester tank, have a welded, removable or hinged cover, as well as a jacket, where steam, water, glycerin or oily liquid acts as a heat carrier. It can also have low-speed (frame with PTFE scrapers, paddle and anchor) and high-speed high-speed mixers of various shapes, such as scraper, paddle, in the form of a squirrel wheel, high-speed (high-speed) mill type and others.
The process of subsequent cooling of the finished product can be carried out by means of cold water of a certain pressure (about 2-3 bar), which enters the entry point into the jacket. In order for the cooling to take place as quickly as possible, between the shirt rim and the rim of the inner brewing tank, a strip is placed on the outer walls from top to bottom in a spiral manner, which directs the flow of the coolant. Also, in the free space under the shirt, a stainless steel coil can be mounted, which is designed to circulate cold water flows that cool the heat carrier and the finished product itself.
A removable mixing device (frame, paddle, spiral, anchor or auger) is mounted on metal brackets on top of the tank so that it does not interfere with the free access of the equipment operator to the brew tank.
The type of mixer can be selected depending on the requirements for the feedstock or at the request of the Client. The drive system of the agitator is a motor-reducer and its power indicators are also selected based on the future consistency and volume of products. The speed mode of the agitator can be either standard (from 28 to 36 rpm) or have a smooth adjustment system carried out by a frequency converter (from 0 to 1500 rpm). Such boilers are supplied with control panels for the mixer, heating and cooling processes, as well as automatic maintenance of the set product temperature.
