Description

An Adjustable Roller Mill Machine for Grains and Derivatives Thereof

TECHNICAL FIELD

The invention generally relates to a roller mill machine which can be adjusted according to the grain size during processing or grinding of the grain and derivatives thereof and enables grinding each grain in a controlled manner.

The invention is particularly related to a roller mill machine which provides adjusting the position of the grinding element constituting the main structure in processing grains and derivatives thereof according to the grain size and by calculating the force applied on it for grinding the grain, allows both making said force stable and controlling thereof.

STATE OF THE ART

Today more than 60 % of the daily nutrition of people consists of grains and products made of grains. Most of these foods consist of bread, pasta; biscuit etc. products obtained from mixing the grains which are processed as flours with various substances.

The process of crushing the grains into flour is called grinding. Grinding grains is a process used since very ancient years. The stone mills used in the grain grinding process since ancient ages are still used today. However, too much labor force and time is required for grinding process in stone mills. For this reason particularly grinding (roller) machines are used in the industry productions wherein grains are used as an intermediate food in flour form.

The roller mill machines consist of units which provide grinding the products. The main structure is certainly composed of the grinding mechanisms. Within the structure of the grinding mechanism, there are grinding elements which enables crushing the grains and making them flour. When we consider that food is a basic need in human life and most of the food consumed consists of directly the grain and derivatives thereof or indirectly the flours obtained thereof, thus the roller mill machines have great importance. During making flour out of the grains and derivatives thereof within the present state of the art namely grinding the grains, grinding elements play a basic role, the pressure force that they apply during crushing and the adjustments thereof are made as a result of the visual and manual control of the obtained product by the miller who operates the roller mill machine, thus this situation which is based on the operator can reduce the operation efficiency together with the breaking and crushing efficiency on the grain products. Also, within the present state of the art the pressure force created between the grinding elements namely the required force value for the grinding process can never be known and calculated. Apart from these disadvantages, another disadvantage or deficiency is that; when a period of time is passed after the grinding process of the roller mill machines in the present state of the art, the changes in the pressure force cannot be recognized and the ideal adjustment cannot be enabled.

A Patent application as 2014/03720 is encountered during patent research of the prior art. Said application is related to a roller mill which is used at the grinding phase of the grains and consists of an automatic feeding unit and oil changing unit. In the application No 2014/03720, a roller mill with a standard grinding mechanism is introduced, except that the feed and oil change unit is automatic. In said application due to the grain size, the positions of the grinding elements are adjusted manually by means of the operators. In this case, it not only leads to loss of labor force but also leads to human based failures. For this reason, the efficiency of the grinding process decreases.

As a result an improvement is made on the roller mill machines, thus new configurations which eliminates the above mentioned disadvantages and brings solutions to the present systems, are required.

PURPOSE OF THE INVENTION

The present invention is related to a roller mill machine which fulfills the abovementioned requirements, eliminates all disadvantages and brings some additional advantages.

The main purpose of the invention; is to provide a product which provides adjusting the position of the grinding element constituting the main structure in processing grains and derivatives thereof according to the grain size and by calculating the force applied on it for grinding the grain, allows both making said force stable and controlling thereof. A purpose of the invention is to determine the applied pressure force on the grain by means of the force sensors and to eliminate the faults due to the human namely the operator.

Another purpose of the invention is that it can be adjusted according to the grain size and stabilizing the applied pressure force thereby it operates with a higher efficiency and requires less labor force.

In order to realize all advantages mentioned above and to be understood from the following detailed description, the present invention is related to a roller mill machine which enables the following; the grinding elements approach to each other or move away from each other main due to the size of the grain and derivatives thereof which enter from the product inlet port by means of the piston and eccentric rod included within the body and said grains and derivatives thereof are grinded together with the compression of the cup springs. Said invention in general consists of a force sensor which measures the pressure force created by the grinding elements during grinding process of the grain over the cup spring and a power control element which enables the pressure force determined by said force sensor to be kept stable and continuous during the process.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, preferred embodiments of the invention roller mill machine (100), are described only for clarifying the subject manner and in a manner such that they do not create any limiting effect.

In Figure 1 , a perspective general view of the inventive roller mill machine (100) assembly is given. Said invention in general consists of the following; grinding elements (4) which breaks, crushes namely grinds the grains that enter through the product inlet port (5) by means of the piston (1 ) and eccentric rod (2) hosed within the main body (6) by means of approaching to each other or moving away from each other according to the grain size, cup spring (3) on which a pressure force is formed by means of the process where said grinding elements (4) compresses namely grinds the grains, a force sensor (10) which determined the severity of the pressure force created on said cup spring (3) and a power control element (20) which enables the required force for grinding the grains in a continuous and stable manner by means of the control panel (7).

In Figure 2, a perspective general view of the grinding mechanism (A) which forms the main structure of the invention roller mill machine (100). In the present state of the art, the grinding elements (4) approaches to each other or move away from each other with a standard distance during the grinding process and thus they grind the grains. Together with a change in the grain size, the operator manually adjusts the distance of the grinding elements (4). This situation leads to the failure due to human and leads to an insufficiently efficient grinding process. On behalf of eliminating this problem, a force sensor (10) is adopted in the neighborhood of the cup spring (3). While the grinding elements (4) grind the grains and derivatives thereof which enter through the product inlet port (5), the approach to each other and together with crushing the grains between them and with compressing the cup spring (3) by the force created, a pressure force is created. In other words, the pressure force created on the cup spring (3) changes due to the grain size. Therefore the grinding elements (4) use a different force value for grinding the grain according to the size of each grain and it transmits this force to the cup spring (3) in an indirect manner. By means of associating the cup spring (3) and force sensor (10) within the roller mill machine (100), the pressure force created on the cup spring (3) is measured namely the force value required for the grinding process according to the grain size is calculated. The operator makes comment according to the relevant grain size after reading this value and determines which force value will be used for grinding said grain. After the operator reads this value, then the required force value for the grinding process according to the grain size is set namely it is applied in a stable and continuous manner. In the roller mill machine (100), this process is performed by the power control element (20) with the help of the control panels (7). Said power control element (20) enables application of the intensity of the force determined by means of the force sensor (10) which is required according to the grain size, in a manner such that it is continuous and stable during the whole grinding process. On the other hand the control panel (7) is used for instant controlling and following the operation of the system. As said power control element (20), servo motors are used. Also in the roller mill machine (100), an electronic protection cover (8) is used for the protection of the automation and electronic systems. The protection of the grinding elements (4) against external factors is performed by means of the protective structure (9).
