Margarine and Shortening Production Line
Margarine and shortening are very popular in the bakery industry，the raw material include palm oil, vegetable oils, animal fat, partially hydrogenated oils and fats, marine oils, palm kernel oil, lard, beef tallow, palm stearin, coconut oil, etc. The main margarine production process are Measuring——Ingredients Configuration——Filtration——Emulsification——Margarine refrigeration——Pin Rotor Kneading——（Resting）——Filling & Packing. The equipment that makes up the Margarine Shortening production plant includes the Votators, Scraped Surface Heat Exchanger，Kneader，Pin Rotor, margarine rest tube, shortening filling and packing machine, homogenizer, emulsifying tank, batching tank, high pressure pump, sterilizer, refrigeration compressor, refrigeration unit, cooling tower, etc.
Where, SPA + SPB + SPC units or SPX-Plus + SPB + SPCH units forms a margarine/shortening crystallization line, which can produce table margarine, shortening, puff pastry margarine and other butter products. The structure of SPA Series SSHE Shortening making machine is unique. After many years optimization, it has high equipment stability, the fineness and finish of the shortening products are leading in China.
In general, SP series margarine/shortening(ghee) production process is：
1. Oil and Fat blends and aqueous phase are pre-weighed in two emulsion holding and mixing vessels. Blending in o the holding/ mixing vessels is done by load cells controlled by PLC control system.
2. Blending processing is controlled by logical computer with touch screen. Each mixing/production tank is equipped with high shear mixer to emulsify the oil and aqueous phases.
3. The mixer is equipped with variable speed drive to reduce the speed for gentle agitation after emulsification is done. The two tanks will be used as production tank and emulsification tank alternatively.
4. The production tank will also function as any product recycle from the production line. The production tank will be the water/chemical tank for the line cleaning and sanitation.
5. The emulsion from the production tank will pass through a twin filter/strainer to ensure no solid will pass in o the final product (GMP requirement).
6. The filter/strainer operates alternatively for filter cleaning. The filtered emulsion is then passed through a pasteurizer (GMP requirement) which consists of three sections of two plate heaters and one retention pipe.
7. The first plate heater will heat the oil emulsion up to pasteurization temperature prior to passing through the retention pipe to provide the necessary holding time.
8. Any emulsion heat to less than the required pasteurization temperature will be recycled back to the production tank.
9 The pasteurized oil emulsion will enter in o the cooling plate heat exchanger to cool down to approximate 5 ~ 7-degree C above the oil melting point to minimize chilling energy.
10. The plate heater is heated by hot water system with temperature control. The plate cooling is done by cooling tower water with automatic temperature regulation valve and PID loops.
11. The emulsion pumping/transfer, up to this point, is done by one high pressure pump. The emulsion is fed into Votator unit and pin rotor in different orders, then lower the temperature to the desired exit temperature for produce the margarine/shortening products needed.
12. The semi-solid oil coming out of the votator machine will be packing or filling by the margarine shortening filling and packaging machine.
SP Series Starch/Sauce Votator Machine Line System
Many prepared foods or other products do not achieve optimal heat transfer due to their consistency. For example, starch, scaue, bulky, sticky, sticky or crystalline products contained in food products can quickly clog or foul certain parts of the heat exchanger. The advantage scrap surface heat exchanger incorporates special designs that make it a model heat exchanger for heating or cooling these products that damage heat transfer. As the product is pumped in o the votator heat exchanger material barrel, the rotor and scraper unit ensures an even temperature distribution, scraping the material away from the heat exchange surface while continuously and gently mixing the product.
The SP series starch cooking system consists of a heating section, a heat preservation section and a cooling section. Depending on the output, configure a single or multiple scrap heat exchangers. After the starch slurry is batched in the batching tank, it is pumped in o the cooking system through the feeding pump. The SP series votator heat exchanger used steam as a heating medium to heat the starch slurry from 25°C to 85°C, whereupon, the starch slurry was kept in the holding section for 2 minutes. The material was cooled from 85°C to 65°C by SSHEs as a cooling device and using ethylene glycol as a cooling medium. The cooled material goes to the next section. The whole system can be cleaned by CIP or SIP to ensure the hygienic index of the whole system.
SPX Custard/Mayonnaise SSHE Machine Line
Custard / mayonnaise / edible sauce production line is a professional system for mayonnaise and the other oil / water phase emulsified ingredients, according to the production process of mayonnaise and the like, the stirring. our equipment is more suitable for mixing products whose viscosity similar to mayonnaise. Emulsification is the core of the production of mayonnaise and Votator series SSHEs, we adopt a production method based on the principle of on-line three-phase micro emulsification, the oil / water phase is divided in o small units, then met in the emulsifying function area, completed the complexation between emulsifier and oil / water emulsion. This design allows the designer to specify the partition of the functional area in the whole scraped surface heat exchanger system, and better to adjust and optimize the whole manufacturing process. Such as in emulsion functional areas, Votator series strengthens emulsifying capacity, makes the oil phase to be emulsified in o microscopic liquid drops and complexing with the aqueous phase and the emulsifier the first time so that getting a stable emulsion system of oil in water, thus solving problems like too wide oil droplet size distribution, poor stability of the product type, and vulnerable to the risk of oil spills etc., which easily cause by the macro emulsification method and mixing stirring modes that interfere with each other.
In addition, SP series scraped surface heat exchangers are also used in other Heating, Cooling, Crystallization, Pasteurization, Sterilization, Gelatinize and Evaporation continuous process.
