Plate heat exchangers are a very important and effective heat transfer equipment to reduce energy consumption in sugar mills. Propellent has a wide range of heating and cooling units: wide-gap plate heat exchangers for fibrous juices, special designed plate heat exchangers for clarifying juices, melts, syrups and molasses.

Molasses is a by-product of the sugar industry. The composition of molasses varies according to the raw materials and processing conditions of sugar making. Molasses mainly contains a lot of fermentable sugars (mainly sucrose), so it is a good raw material for fermentation. It can be used as the substrate or base material of fermented products such as yeast, monosodium glutamate, organic acid, etc., and can be used as the raw material of some foods and animal feed.

Cooling the molasses before entering the storage tank is a key measure to prevent the deterioration of molasses during storage. The temperature for processing molasses is usually not too high, so it is a good choice to use SS 316 for the plates and EPDM for the rubber pads. Due to the relatively high viscosity of molasses, the Propellent heat exchanger adopts specially designed non-contact wide flow channel plates, and the wide gap plate with a depth of 6-12 mm allows high-speed flow (through particles up to 5 mm in diameter) to make Molasses can pass through without stagnation. The design of Propellent can make full use of the heat in the evaporation, condensation, cooling and heating sections. For example, the repeated use of excess exhaust gas and condensed products is achieved with minimal temperature differences.

Different juice flows require constant heat transfer from the initial juice to the final syrup. Propellent products can help you recover more heat load from your process, helping you save energy and production costs.
