Avail from us, our range of mini dal mills is use for making carrying different processes cleaning and grading, pitting, pre-treatment with Oil & water, conditioning, de- husking & splitting.
Techno Agencies offer mini dal mill. This mini dal mill is simple in construction and easy to operate & maintain. It consist of horizontal tapered roller is covered with emery coating, surrounded by a screen through which the husk is discharged. The shelled dal passes through an aspirating fan on the oscillating sieve unit, where appropriate grading of dal is done It is run on only 2 H.P. Automatic arrangement are made for collection of de husked and split dal , un de husked and split dal, un de husked dal , brackens, husk in separate containers and bags. This machine offers dust free operation, does not cause pollution, retains proteins, natural shine etc ... motor is provide with a pulley and is mount at the bottom of the stand with V-belt to drive it. The motor requirement is of 2 HP single / three phases.

Construction of Mini Dal Mill

This mini dal mill is simple in construction & easy to operate & Maintains. it consist of horizontal tapered Roller the roller is covered with emery coating surrounded by screen through which husk powder is discharged. The shelled dals pass through aspirating fan on oscillating sieve unit where appropriate grading of dals is done.
The vibratory sieves are provided with different size holes to match the requirements of the type of dal being processed. The vibration are included b a cam operated link which is mounted on a counter shaft ( Motor Derived Shaft )
With this mini dal mill Techno Agencies is provided paddle type screw mixer in all Mild steel construction with worm shaft.

Process of mini dal mill

Process of de-husking is doing in two major steps. In the first step the cleaned and size graded grain are scarify followed by oil addition and sun / mechanical drying. In the second step, the removal of husk and splitting into two cotyledons is doing by passing the material through versatile dal de-husker. This de-husker gives 2-4% higher yield of good quality Dal, than the traditional Dal mill. This method developed by Techno Agencies is less laborious, requires less time and reduces losses during de-husking. One of these methods developed and ready for commercialization is 'MINI DAL MILL'. The technical up gradation & cost economics of the 'MINI DAL MILL combined with facilities of Grader cum Cleaner can prove to be a boon to the farmers. This unit installed near the farm itself. Process on Dal mill Cleaning and grading: This unit consists of a vibratory inclined sieve, hopper, grain collector, waste collector and motor. The vibratory sieves are providing with different size holes to match the requirements of the type of Dal being process. The vibrations are inducing by a cam-operated link, which is mounts on a motor driven shaft.

Pitting Process For Mini Dal Mill

An emery roller machine is use to obtain cracking and scratching of clean dal passing through it. For loosening, the husk to facilitate the subsequent oil penetration this is required. Gradually the clearance between the emery roller and cage (housing) is narrow from inlet to outlet. Cracking and scratching of husk takes place mainly by friction between dal and emery as the material is passing through the narrowing clearance. During the operation, some of the dal are de-husk and split which are separate by sieving.

Pretreatment with Oil & Water

A screw conveyor allows passing the scratched or spitted material through it and mixing of some edible oil like linseed oil is complete. The linseed oil is use at the rate of 1.5 to 2.5 kg/tones of dal . These are keeping on floors for about 12 hours to diffuse the oil.

Conditioning of dals

dal are condition by alternate wetting and drying. Moisture (3.5%) is adding to the dal after sun drying for a certain period and tempering is doing for about eight hours. The grain is dry in the sun again. By allowing water to drop from an overhead tank on the dal, which are passing through the screw conveyor addition of moisture to the dal, are achieving. Until all dal are sufficiently conditioned the whole process of alternate wetting and drying is continued for two to four days. dal are finally dry to about 10 to 12% moisture content.

De-Husking and splitting of dal

For De-husking of conditioned dal emery rollers called as Gota machine are used. In one pass or single operation, about 50% of dal are de-husked. De-husked dal are splitting into two parts. De-husked split dal are separate by sieving and the husk is aspirate off. Un-split de-husked dal and tail dal are again de-husk and milled in a similar way. Until the running dal are de-husked and split of the whole process is repeated two or three times.

Pre Milling of dal

To obtain best results during de-husking and splitting of dal in the Dal de husking machine in Techno brand mini Dal mills, latest model improved version, pre milling including grading of dal size wise is very essential. The raw dal are first clean of dust, chaff, stones and other extraneous materials. Sieves grade cleaned dal or dal graded and soaked in water in cement's tanks having 6" depth. Height of dal soaked be 5" and the water level should be 1" above the dal . Soak dal are taken out of the water after specific time and put on the sieve. Swollen dal which do not pass through sieve (from which un-swollen dal earlier passed through the same) are ready for heaping in shade whereas the dal which pass through the same sieves. Then these dal are ready for heaping in shade. Degree of happing of swollen dal in shade should be 30 to 40. This process should be continuing until the dal are swill to the desired extent. There after the dal are in thin layers in the open sun drying. Duration of sun drying of dal vary according to weather condition prevailing at the time of processing. After sun drying, the dal are again heap in shade so moisture contents in the dal may become uniform as need in them for de-husking. Then the dal are graded again fed in to the dal de husking machine in Techno Mini Dal Mill in graded lots to achieve he best results with minimum brokenness. For the guidance of the entrepreneurs, the process of details of pre-milling of dal after proper cleaning is show here after in a tabulated chart.
Note: -
  • Period of soaking in water will vary according to weather condition and quality of pulses ( Dal ).
  • Duration of sun drying will vary according to weather condition.
  • Pulses ( Dal ) should not be warm at the time of De-husking/splitting.
  • Pulses ( Dal ) should be de-husk and split in graded lots only.
  • Pulses ( Dal ) shown at one & two must be dry within 3 days to get better results. Their processing in any season should be avoiding.
  • The de-husked pulses ( Dal ) mixed with the un-husked pulses ( Dal ) and the husks are again de-husked in the Techno brand mini Dal mill as usual. In second pass all, the pulses ( Dal ) are de-husked.
