MILLS

TECHNICAL FIELD

The invention relates to wheat impact scourer and dampening machine that allows peeling of the husks of the grains, removal of foreign materials such as lint, dust, etc. remaining on the grain and dampening of the grain before grinding in the same machine before the milling process in grain milling systems.

PRIOR ART

In grain grinding mill systems, after the rough cleaning processes, the grains are passed through the peeling and dampening units prior to grinding and are made ready for the milling process.

The process of peeling the husks of the grains, which have undergone rough cleaning for grinding, is carried out with the principle of rubbing. The grains are strongly pressed and rubbed against the sieve forming the outer frame with the help of a horizontal rotor. At the same time, the grains are pressed and rubbed against each other with the intense friction created. Grains are compressed and rubbed with blades attached to the rotor. At the end of all these rubbing and rubbing processes, the grains are separated from both their shells and foreign materials such as lint, dust, etc. on them and transferred to the dampening units.

Dampening is the process of conditioning the grain by the adding or removing of water in order to adjust the moisture level of the grain and make the grain most suitable for grinding. The grain moisture absorption rate and proportion are important in the dampening process. The dampening process is performed to balance the flour extraction and bran ratio. This process is carried out with applications aimed at increasing the moisture absorption of the grain and increasing the extraction (yield) by using water at different temperatures in the current technology. The water given during the dampening process cannot be absorbed by the grain due to the nature of the grain. Some of the supplied water may remain free in the system. The free water remaining in traditional methods causes mould, bacteria, etc. formation and bad odour in the systems.

In the text of the patent no. US2011003065, the grains are moistened by passing them through a helical machine in such a way that the waiting time in the machine is extended, and an attempt is made to facilitate the peeling of the shells in the next operation. Here, however, multiple units and long run times are required.

BRIEF DESCRIPTION OF THE INVENTION

A wheat impact scourer and dampener has been developed for grain mills, which are the subject of the invention, with the intention of carrying out the processes of peeling the husks of the grains, removing foreign materials such as lint, dust, etc. remaining on the grain and dampening the grain in the same machine with high efficiency prior to milling operations in grain milling systems.

In the developed wheat impact scourer and dampening machine, the peeling and dampening processes of the grains are carried out in the same unit. In this way, space usage and energy consumption in the facility are reduced.

Thanks to the high-pressure water feed used in the developed peeling and dampening machine, both the peeling efficiency is increased and the water consumption used during dampening is reduced.

Thanks to the helical transport developed in the wheat impact scourer and dampening machine developed, it is ensured that the husks and foreign materials separated from the grains and possible excess dampening water are easily removed from the system.

DETAILED DESCRIPTION OF THE INVENTION

The wheat impact scourer and dampening machine for the grain mills of the present invention contains parts and sections of the peeling section (1 ) where the husk on the grains is peeled off and foreign materials such as lint and dust are removed from the grains, the dampening section (2) where the dampening process is carried out to make the peeled grains ready for the grinding process, the outer liner (3) that is preferably made of metal and positioned on the outermost layer of the peeling section (1 ) and the dampening section ( 2), the inner mesh wire (4) that is preferably made of metal and driven to rotate around its own axis, the carrier helix (5) that is connected to the mesh wire (4), the product inlet (6) where grains are fed into the machine, the rotor shaft (7) that is positioned at the centre of the machine and driven to rotate around its own axis, the feeding screw (8) that transfers the grains fed into the machine from the inlet to the inner parts, at least one palette (9) that is preferably made of metal and connected to the rotor shaft (7) in order to ensure that the grains are moved in a way suitable for the peeling process, the contact surface (10) that is formed with rough surface and connected to the palette (9) to increase the contact surface with the grains, at least one spray head (11 ) that is connected to rotor shaft to ensure the pulverization of the pressurized water towards the grains, pressurized water inlet (12) that allows the pressurized water to be fed to the spray head (11 ) to enter the machine, the waste outlet that ensures the transfer of excess water and foreign materials separated from the grains out of the machine, the product outlet where peeled and tempered grains are transferred out of the machine prior to milling.

The outer sheet screen (3) developed in the peeling and dampening machine for the grain mills, which is the subject of the invention, is the part preferably made of metal and positioned on the machine in such a way as to provide the outer casing of the peeling section (1) and the dampening section (2) of the machine and all the equipment within these sections.

The inner liner (4) developed in the peeling and dampening machine for the grain mills, which is the subject of the invention, is the part that is preferably made of metal in one piece along the peeling section (1 ) and the dampening section (2) of the machine. The inner liner (4) is the part that is formed in a way that the section of it remaining in the peeling section (1 ) has sieving holes on it in order to ensure that the husks peeled, and the foreign materials removed from the grains are transferred to the outside of the inner liner (4), and the section remaining in the dampening section (2) has no holes on it. The inner liner (4) is the engine driven part that rotates around its own axis and in the opposite direction of the rotor shaft (7).

The carrier helix (5) developed in the peeling and dampening machine for the grain mills, which is the subject of the invention, is a section preferably made of metal and is manufactured on the inner liner (4) as connected to the inner liner (4). The carrier helix (5) is the part that is manufactured on the inner liner (4), preferably in a spiral form and preferably in a continuous form. The carrier helix (5) is the section that rotates together with the inner liner (4) in the same direction so that the materials such as husk, lint, dust, etc. transferred from the perforated sections of the inner liner (4) to the outside of the inner liner (4) are transferred to the waste outlet between the inner liner (4) and the outer liner (3).

The rotor shaft (7), developed in the peeling and dampening machine for the grain mills, which is the subject of the invention, is the engine-driven part that rotates around its own axis and in the opposite direction of the inner liner (7). The rotor shaft (7) is the part which has at least one carrier vane (9) containing at least one contact surface (10) and at least one spray head (11 ) connected to it.

The carrier vane (9) developed in the peeling and dampening machine for the grain mills, which is the subject of the invention, is the part connected to the rotor shaft (7) and has a rough contact surface (10) preferably made of metal connected to it and rotates together with the rotor shaft (7).

The contact surface (10) developed in the peeling and dampening machine for the grain mills, which is the subject of the invention, is the part preferably made of metal, the surface of which is formed as rough to increase the contact with the grains, and connected to the carrier vane (9).

The contact surface (10) is connected to the carrier vane (9) and ensures that the grains are pressed towards each other and the rubbing force is increased, as well as extending the component life by acting as a coating in the grain contact area of the carrier vane (9).

The spray head (11 ) developed in the peeling and dampening machine for the grain mills, which is the subject of the invention, is the part that is connected to the rotor shaft (7) and ensures that the water at the desired pressure value is sprayed on the grains taken into the machine. The spray head (11 ) is a replaceable part on the rotor shaft (7), allowing the use of a nozzle suitable for different pressure and water amount depending on the need in the peeling (1 ) and dampening sections of the machine (2) or the type of grain fed into the machine.

The pressurized water inlet (12) developed in the peeling and dampening machine for the grain mills, which is the subject of the invention, is the section that allows the pressurized water to be transferred to the spray head (11 ) located on the rotor shaft (7) to enter the machine at the desired pressure and amount.

Thanks to the spray head (11 ) used in the peeling and dampening machine for the grain mills, which is the subject of the invention, deformation is created on the husks of the grains fed into the machine in the peeling section (1 ) with high-pressure water, thus enabling the peeling process to be carried out with high efficiency. Thanks to the use of the spray nozzle (11 ) and the transfer of water by spraying onto the grains that have been peeled and free from foreign substances in the dampening section (2), moisture retention of the grains is facilitated by reducing the surface tension of the water and increasing the contact surface. In this way, water consumption is reduced and also possible excess water that may remain in the machine is prevented by performing the dampening process with a much lower amount of water than the amount of water used in the current technique.

The outer shell integrity of the grain is disrupted by the rough formation of the contact surface (10), which is the subject of the invention, which is connected to the carrier pallet (9) used in the peeling and dampening machine for the grain mills. In this case, the volume of the husks increases with the effect of the water coming from the spray head (9), and as a result of rubbing the grains with each other, with the inner surface of the inner liner (4), with the contact surface (10) of the carrier pallet (9) and pressurized water, faster husk peeling is achieved.

Thanks to the helical structure and rotational movement of the carrier helix (5) used in the peeling and dampening machine for the grain mills, which is the subject of the invention, the husk, foreign matter and excess water fed into the machine are directed to the waste outlet and removed to the outside of the machine. Thus, the accumulation of undesired substances in the machine is prevented and the recycling of excess water is ensured.
