The price of the industrial nut roasting machine is determined based on the production capacity per hour, the alloy of the cooking drum (steel 304 or refractory iron), the type of burner and the intelligent temperature control system, and there is a significant difference in the scale of the workshop to the continuous lines of the factory. Based on the executive estimates of the processing lines, the thickness of the drum sheet and the thermal insulation structure of the body play the biggest role in the durability of the machine and prevent the drop in energy efficiency. In manufacturing this equipment, Hilda Sanat Toos Machinery Company has made the matching of the heat transfer rate with the moisture level of different varieties of pistachio, almond and seeds as the basis of engineering design in order to prevent burning of the shell or rawness of the core.
In the process of setting up dry fruit processing factories in hubs such as Mashhad, Tabriz, Rafsanjan and industrial towns of the central province, we have always seen that the primary focus of buyers is only on the initial invoice figure. In practice, it has been observed that reducing the quality of the drum or using non-standard parts of the motor-gearbox, in less than six months, the cost of repairs and heat loss increases to several times the difference of the initial purchase price. A careful examination of the manufacturer's parameters is the only way to achieve a reasonable return on investment rate in this industry.
body material and cooking drum; The technical difference between food steel and industrial sheets
The most important engineering variable in the pricing of roasting systems is the material used in the rotating drum. In Hilda Sanat Tos machine building, experimental studies of the projects have shown that the constant contact of salt, lemon juice, vinegar and other flavorings with the hot surface of the drum greatly increases the corrosion rate.

Nominal capacity and working efficiency of the device in the production cycle
Industrial nut roasting machines are generally produced in batch capacities, which are calculated in kilograms per part or daily tonnage. The scale of production determines the power of the structure's skeleton, the power of the electric motor and the size of the central axis.
Workshop and semi-industrial capacity (20 to 70 kg)
This category of machinery is used for local packaging workshops, confectioneries and large dry fruit processing stores. The price of these models is determined according to the single-phase or three-phase electric motor and the simplicity of the load transfer system, and it is suitable for units with a high variety of products and limited circulation.
All industrial lines and high tonnage (100 to 500 kg/hour)
In large pistachio, hazelnut, peanut and sunflower seed industrial processing lines, high capacity machines are equipped with heavy duty inverters, helical industrial gearboxes and double stud chassis. In this structural model, changes in the global price of heavy metals and automation equipment have a rapid effect on the finished price of the car.
Thermal system technology, burner type and intelligent temperature monitoring
The process of roasting nuts is definitely dependent on the thermal behavior of the device; The sudden thermal shock causes the volatile oils of the kernels to burn, and insufficient heat preserves the middle moisture and destroys the texture's crispiness.
Smart burners with blower and atmospheric system
The type of burner installed on the device is one of the key factors of temperature stability. Industrial blower burners provide the possibility of adjusting the air-to-fuel ratio and provide clean and soot-free burning. In contrast, atmospheric tube burners provide less control over flame length and increase gas consumption during long shifts.
Digital control system, inverter and PLC automation
Equipping the device with accurate temperature control systems (PID digital thermostats) and sheathed thermocouple sensors enables accurate recording of the load brain temperature. Also, the addition of the motor speed control drive (inverter) allows the operator to adjust the drum rotation speed for sensitive seeds such as Japanese seeds, pistachios or walnuts; A feature that prevents mechanical damage to the product.
The effect of the quality of mechanical components and actuators on long-term costs
A dried fruit roasting line often continues to work in 8-16 hour shifts. Depreciation of rotating parts and bearings can cause unwanted stoppage of production lines.
Bearings, anti-heat bearings and electric motors
The bearings connected to the drum shaft are exposed to high thermal stresses due to their proximity to the continuous burner. The use of specialized industrial bearings resistant to temperatures above 200 degrees Celsius and motogen electric motors with all-copper windings add significant technical value to the device and prevent gripping during operation.
power transmission system; Direct coupling against chains and belts
The method of power transmission from the gearbox to the drum shaft determines the vibration, operating noise and lifespan of the device. In practice, it has been observed that direct solar or helical gearbox systems with rigid or flexible coupling reduce energy loss and eliminate the need for successive chain adjustments.

The finished price of the complete nut roasting line is not summed up in the roasting machine alone; The business process is dependent on auxiliary equipment:
Criteria for choosing the right nut roasting machine for factories
Hilda Sanat Toos Machinery Industry suggests that the following technical specifications should be considered as a checklist before making a final decision on capacity and price inquiry:
- Checking the alignment of the drum with the chassis to prevent uneven wear
- Ensuring the complete exit of combustion gases through a separate exhaust without mixing with the internal cooking air
- The presence of reverse rotation of the drum for quick and automatic unloading of the load without manual intervention
- Availability of spare parts, real warranty of the structure and engine, and specialized support services in case of technical failure
