Roasters

Roasters

Mecmar grain roasters are made with high quality materials and components, to last in the long time and to ensure great reliability and excellent performance.

The strong connection with the Italian agricultural tradition that characterizes Mecmar, combined with the continuous dialogue with users of the company’s proposals, contributed and still contribute to the development of efficient and functional solutions, to facilitate the most different roasting needs.

Some examples are the realization of grain roasting fixed and mobile systems both simple and complex, roasters in stainless steel, roasters equipped with heat exchangers.

The compact design of Mecmar grain roasters is specifically designed to ensure that transport and positioning of the machine are not a problem, but an easy and quick operation.

Thanks to Mecmar grain roasters, cereals of various types are treated homogeneously: the roasting process is performed in an optimal way, in order to guarantee numerous benefits. Many cereals and legumes, such as soy, are extremely interesting for animal nutrition thanks to their high biological value of proteins, vitamins, fats and minerals. It is therefore a question of eliminating those anti-nutritional elements that hinder the assimilation of nutritional elements and this is where grain roasters come into play.

With the roasting process, in fact, trypsin inhibitors that interfere with the digestion of proteins are minimized without affecting the contents of fats and vitamins. In addition, bypass proteins are increased. All this makes cereals more appetizing for animals which, eating better, are more likely to grow strong and healthy.

How

How it works

Roaster
Product flow
Air flow

Mecmar grain roasters carry out a delicate, homogeneous and rapid treatment on any type of cereal (soy, beans, field beans, sorghum, corn, etc.), in order to adapt to various needs and always guarantee quality and efficiency.

The product to treat is loaded into the hopper and is dosed inside the roaster through a star valve. The conveyor belt gently accompanies the grains from the entrance to the machine outlet: during this process, the cereal is treated homogeneously by a flow of hot air which passes through a perforated bed, roasting the cereal. Depending on the needs, the heat can be supplied by oil, gas or LPG burners or by a heat exchanger.

To increase efficiency and decrease energy consumption, the hot air leaving the machine is recovered to preheat the air used for roasting. The roasting process is automated thanks to the use of inverters and controlled by a network of sensors that allow to optimize the roasting process and to intervene in complete safety even in case of emergency.

Care

Care for details

Mecmar starts from a strong awareness: in order to guarantee the best result, it is necessary to offer a technologically innovative equipment, reliable and simple to use. In fact, in order to look to the future, the best way to go is to work intelligently and take care of every detail.

Mecmar has developed the design of its grain roasters in order to facilitate their transport and positioning, but also to minimize the time of installation. For Mecmar it is important to ensure safe, resistant and easy-to-use machines. For this reason, the best components have been chosen for Mecmar grain roasters:

Burner

Professional burners by RIELLO, synonymous with professionalism recognized Worldwide. 

Valves
Inspection portholes
Sensors
Fire estinguishing system
Option

Features

Riello professional burner
RIELLO professional burner made in Italy. Having used the same type of burners on our dryers for over 40 years, we are more than convinced of the technology of this heating system
x
Main fan
This fan provides the main thrust to the air to toast and to evenly mix the product during the treatment
x
Auxiliary fan for the burner
This fan is in the larger series (T20 and T50) and provides higher pressure to the burner for developing a better flame
x
Automatic minimum and maximum levels
Supplied on all roasters, these two levels can be connected to a loading screw so that the roaster automatically loads
x
Electric motors driven by inverter
The soybean flow is controlled by 2 gear motors whose speed can be changed through a touch screen
x
Chain break sensor
Standard on all roasters, a sensor continuously monitors the actual operation of the conveyor belt and alerts of any breaks or jams in the chain
x
Fire-fighting system
Standard on all roasters, a sensor continuously monitors the actual operation of the conveyor belt and alerts of any breaks or jams in the chain
x
Air temperature sensors
2 temperature sensors continuously check that the process temperatures are constant and a safety system will alert in case of overtemperatures
x
Product temperature sensor
1 temperature sensor at the outlet of the roaster controls the temperature of the toasted product to give a continuous feedback on how the toasting is progressing
x
Outlet rotary valve (optional)
Upon request, a rotary valve can be mounted at the product outlet for preventing any heat loss from the outlet
x
Regulation of the heat recovery
This controls how much heat can be recovered from the hot chamber of the roaster
x
Heat recovery system
All roasters include an air-air heat exchanger to preheat the air by using the high temperatures of the fumes at the outlet before heating the air with the burner
x
Inspection door
Used to intervene or only visually check an otherwise inaccessible area
x
Exhaust air outlet
The hot air coming out of the roaster is conveyed by 2 pipes and can be made available for future use of a heat exchanger or other
x
Control panel
Available in electromechanical and touch screen versions, this allows you to control the roaster and, if necessary, to interface it with other external loading/unloading systems
x
Inspection portholes
To visually observe the beans toasting
x
