Bagging conveyors are designed to provide efficient and reliable movement of materials and containers within the packaging process.

Extracted material has tendency for retaining the solvent with it and this solvent has to be recovered. The retention varies from 25% to 30% on weight of material extracted. The basic principles involved in desolventisation is indirect/direct heating of material with steam to a temperature well above the boiling point of solvent and thus ensuring that no solvent is left over with the material. Vapours of solvent are then sent to the condensers via scrubber where solvent is condensed.

The D.T. consists of a vertical cylindrical vessel with horizontal jacketed compartments i.e. Double Bottoms and a central rotating vertical shaft on which blades are mounted to sweeps in each compartment. The Material to be desolventised and toasted is fed in to the top compartment of D.T and heated with open steam.

Salient Features

1. Intimate contact of material with hot surface helps in properly desolventising the extracted meal i.e evaporation of hexane from the meal and there by maintaining quality of the finished product.
2. Steam consumption is also reduced as steam circulates internally.
3. Mechanical/Pneumatic level controlling system maintains minimum bed height for complete desolventisation within short contact time.
4. Vapour outlet from DT is passed to economizer thus maintaining energy efficient process.

Most modernized unit with updated features to process flakes to make porous cake good for solvent extraction and squeeze partial oil from highly oil content seeds like Mustard, Sunflower etc. Expander also processes castor expeller cake to convert in to porous cake good for solvent extraction. Various models available with capacity range from 50TPD to 1000TPD

Extractor is a machine with slow moving articulated band conveyor inside a totally enclosed chamber. The band conveyor is lined with perforated sheet, covered with stainless steel wire mesh for easy percolation of Miscella. The Band Conveyor moves on the rail provided inside the extractor. A series of sprays are located above the band conveyor for spraying miscella and solvent on top of the moving material bed of the extractor. During the movement of the bed through the extractor it is washed continuously at various points with miscella of decreasing concentration and finally with a fresh solvent in a counter current manner by means of sprays kept in a line over the meal bed.

The miscella percolates through the meal bed, passed through the perforated bottom and collects in various hoppers kept below the bed which ultimately flows to the miscella holding tank. The extracted meal from the band conveyor falls into the discharge bin and conveyed to the desolventising section by vapour seal chain conveyor.

The prepared Raw materials from the Preparatory section are conveyed by Redler Conveyor to the Extractor via Rotary Valve which regulates the feed of material to Feed Bin. Level indicators are provided on the Feed Hopper to control low and high level of the materials in extractor.

These machines are suitable for efficient cleaning of all types of grains and seed. Gentle vibratory feeder and the belt guard provide efficient cleaning of grain without causing any damage to the particles. The graded material and the impurities like stones and sand are automatically discharged in separate chutes and are high in functionality.

It is used to cook the material before it enters flaker machine. The cooker consists on a vertical cylindrical body equipped by heating plates. A central shaft mixes the products at each stage. This set is controlled by a gear box. It is installed in the upper part.

The product is conveyed to the upper part of the equipment and pass successively at each to another by gravity. A pneumatically-controlled hatch regulates the flow rate depending on a level of seed pre-selected at each stage. This system allows a self-regulated way by the output of the extractor or feeder to be installed under the equipment: any output's variation is automatically reflected on the input of the cooker without any intervention of the operator.

Each stage is equipped with a stainless steel inspection door with false door enabling opening full stage to make a visual inspection or to take a sample, for example. Following the layout, we can supply an equipment with unlined hatches and according to the customer's wishes.

It is used for breaking the oil seeds before sending it to the cooker in order to reduce the load enhance the capacity of the flaker and also and improve the quality of the flakes.

To mill the oil seeds into thin flakes by roller flaker mill, which can extend the surface area, make the oil material more plastic for cooking process. It also helps in enhancing the capacity of expander.

Mixture of oil and solvent obtained in the extractor is known as Miscella and it normally contains 15% to 25% of oil in solvent. The rich miscella from extractor is collected in tanks from where it is pumped to the distillation column. It is kept under vacuum by means of a series of steam ejector. The miscella passing through tubes of evaporator is heated by jacketed steam and thus hexane is turned into vapour immediately. The vapours are led to the condensers via separators. The concentrated miscella passes on to the Oil Preheater to raise the temperature to 100ºC and then to stripping column for final removal of the last traces of solvent from oil. The vapours from the equipments are condensed in the condenser.

This equipment is used for drying/ cooling of expanded material by cross air flow before sending it to solvent extraction section. It consists of blowers, cyclones, screw conveyors and a material conveying system.

It is designed to hull, remove shells, separate and re-separate your product. The equipment features low electricity consumption, compact structure, small area occupation & low damage of seeds and kernels.

High quality elevators and conveyors are used for feeding of seed/nuts & cakes into expeller and other cleaning & decorticating machinery. Their usage brings a significant reduction in manpower involved in feeding the seeds
