Turnkey Projects

Detergents are used for many purposes, and there are wide range of substrates e.g. surface to be cleaned and of soils. We mainly focus on main substrate i.e. textile fabrics.

In Turnkey Detergent Plants, for manufacturing of detergents more than 40 & odd ingredients can be used. A detergent is a formulation comprising essential constituents viz. surface active agents, builders, boosters, fillers and auxiliaries. Each of these basic materials has its advantages and disadvantages

SHACHI ENGINEERING PVT. LTD. not only serve the detergent industry by providing spray dryers [Nozzle/disc atomizers] but with the team of experts and experience technocrats, we help our clients by providing technical know-how for detergent formulations with backward integration for the important raw material manufacturing e.g. sulphation and sulphonation by batch process. We provide technical know-how to our esteemed clients considering :-

As SHACHI ENGINEERING PVT. LTD. is a firm believer in quality, we provide latest analytical methods for raw materials, intermediates and finished goods.

We, being dedicated, experienced and experts provide our services to our clients for detergent manufacturing all under one roof.

Not only we are happy by supplying the technical know-how and detergent manufacturing plants, we are committed to help our clients for up-gradation, cost reduction, optimum output with excellent results of the detergents. SHACHI ENGINEERING PVT. LTD. takes special care for incorporation of perborates, optical brighteners, perfumes and enzymes in spray dried detergent powder.

SHACHI ENGINEERING PVT. LTD. observe some guidelines as to quality control of spray dried powder viz.

For spray drying of detergent powder, machine mixed powder is converted into slurry of desired solid contents. Then after de-aeration [if required] of slurry, it is filtered to get consistent viscosity and this slurry is pumped and sprayed through nozzle. Sprayed slurry is dried by countercurrent / co-current of hot air.

This spray dried powder with appropriate cooling is mixed with perborates, optical brighteners, enzymes and perfumes. This material is then packed in desired packing.

Total operations of detergent powder manufacturing to packing of spray dried powder can be fully automatic, semiautomatic or manual depending on the client's requirement.

Milk Powder Plant consists of a multiple effect evaporator with or without pasteurizer and a spray dryer. Multiple effect evaporator is used for concentration of dilute liquid milk having initial concentration in the range of 8- 10%. Dilute milk is concentrated upto about 46-48% concentration. This concentrated milk is then treated in spray dryer. The liquid milk is converted into powder form having concentration of about 97-99%.

Multi-effect evaporator system used for milk concentration is a combination of two or more evaporative effects acting as an evaporator battery. An effect consists of a Calendria and a vapour liquid separator. Calendria is a shell having a number of tubes bundled together. Steam is used to evaporate water present in dilute milk, concentrating it to desired degree of concentration. Steam is circulated in the shell of calendria. Milk in the tubes gets heated and evaporated due to steam surrounding the tubes. Vapour along with concentrated milk is passed over to vapour liquid separator. Vapour is separated and allowed to pass over to next calendria as a heating medium for that effect. The concentrated milk separated from vapour in vapour liquid separator is fed to next evaporator for further concentration and so on.

Finally the milk having desired concentration level is collected from the last effect vapour separator. The vapour is passed over to the condenser. Cooling water is used as a cooling medium in condenser. A part of steam from the first effect is fed to pasteurizer via a pre-heater. A part of steam/ vapour from second effect is fed to thermo-compressor. Also, we can pass over a part of vapour from the first effect to thermo-compressor instead of second.

The evaporation system is kept under vacuum with the help of a vacuum pump. Vacuum pump is connected to the condenser.

Now this concentrated milk is passed over to Spray Dryer for powder formation. It is stored in a balance tank It is then fed to the Atomization system through a variable speed feed Pump. The liquid feed is atomized and forms a mist. The mist comes in contact with the Hot Air entering the chamber in a co-current fashion through a specially designed air distributor. The air distributor, supplied by SHACHI ensures the uniform spread of hot air and uniform drying of the particles. The dried powder is separated and discharged below chamber through an air lock rotary valve.

The fines entrained with the exhaust air from the chamber is separated in a high efficiency cyclone separator and discharged through the Rotary Air Lock Valve. The powder discharged from the chamber and high efficiency cyclone separator is conveyed to the bagging cyclone with the help of a conveying air blower. The exhaust from the bagging cyclone is fed back to the main cyclone to ensure further separation of the little powder entrained in the exhaust. The clean exhaust air coming out is then vented to the atmosphere.

This entire operation of concentration and drying of milk and producing milk powder is controlled by locally mounted control panel.

Chemical Industries use a large amount of process water and produce liquid wastes containing lots of chemicals which may be harmful to living organizations.

These untreated liquid wastes are generally thrown into a river or sea water. Where they pollute aquatic life and also causing severe problems to respiratory systems, digestive systems and eyes in humans.

Shachi provides Zero Liquid Discharge Plants, which are a combination of multi effect evaporators, and Spray Drying Plant. Dilute wastes streams are concentrated in evaporators battery and then fed to the spray drying plant. The concentrated liquids is converted into powder, which can be used as a by - product and can be dumped as land filler.
