Dual-effect Concentrator
I. Applicable Range
This concentrator is suitable for the concentration of liquids such as starch, monosodium glutamate, dairy products, and chemicals. It is particularly suitable for the low-temperature vacuum concentration of heat-sensitive materials. After careful calculation and meticulous design improvements by our company, it offers more benefits than the original features.
II. Equipment Composition
The dual-effect concentrator is primarily composed of two tube-type heaters, two evaporators, a circulating tube, a condenser, a receiver tank, and other auxiliary equipment.
III. Key Features
1Energy-saving benefitsSJN-1000Type Calculation, saves about 1 ton of steam per year3500tons, save cooling water9Approximately ten thousand tons, energy-saving8Approximately 10,000 degrees, equivalent to RMB10-15Ten thousand yuan (compared to single-effect).
2Our concentrator utilizes an external heat natural circulation system and vacuum negative pressure evaporation method, featuring fast evaporation speed and high concentration ratio, up to1.2-1.35(General Chinese herbal extracts), no need for open pot to collect the extract.
3This concentrator employs simultaneous two-effect evaporation, utilizing the secondary steam, which allows your factory to save on boiler investment and energy consumption, reducing energy consumption compared to single-effect concentrators.50%Within less than a year, the energy-saving costs can recoup the entire investment in this concentrator.
4Multi-functional operation features:1Recyclable Alcohol Concentration80%Left and right;2Single-effect and double-effect units can be repeatedly used in a coalescence pot to collect paste.3Can be fed intermittently or continuously.
5This concentrator features a special design, producing a concentrated material with a rich flavor and uniform paste texture. It allows for concentration without foam in a sealed state, minimizing material loss and contamination. Concentration is done on the same day as the material is used, preventing coking and making cleaning easy. Simply open the top and bottom covers of the heater for cleaning, and it saves labor, as one person can operate it.
6All contact parts of this concentrator are made of stainless steel.SUS304Manufacturing, all external parts of the heater and evaporator are insulated with polyurethane foam, and the outer surface is treated with a sandblasted matte finish, in compliance withGMPStandard.
