Travelling Heat Oven – Parmar Machine and Technologies

STRUCTURE: The oven structure shall mainly be fabricated from 75 x 40mm channels and 50 x 50mm angles. Cross frame components shall be fabricated and reinforced with 6mm thick gusset plates. These frames shall be bolted to each other at 5ft (five feet) intervals using 50mm x 50mm angles. The structure shall span 50 ft and be formed with 11 units.
PANELS: The two side panels and the top panel shall be fabricated from 18 SWG CRCA MS sheets. A 4" gap between these plates shall be filled with mineral wool to serve as insulation. Specially perforated sheet metal channels shall be used. These sheets are intended to reduce heat connection at the edges. Forming the bottom part of the oven, it shall be closed by an 18 SWG CRCA panel with 4" insulation, serving as protection for the return chain and reducing heat loss to the atmosphere.
CONVEYOR: A chain conveyor (600 cc Type) with variable speed drive arrangement will be used for feeding at one end and unloading at the other end.
HEATING CHAMBER: The heating chamber shall be mounted at the top of the oven. The entire chamber shall be lined with super fine mineral wool from the outside. The gas burner and complete control system shall be mounted on the chamber. There shall be one stainless steel component.
DUCTS: The air circulation ducts shall be fabricated from 18 SWG CRCA sheet and shall have perforated holes on one side. Adjustable dampers shall be placed at appropriate intervals to enable uniform air circulation.
FANS: All fans shall be fabricated from 10 SWG CRCA MS sheets with suitable reinforcements. Fan impellers shall be dynamically balanced to ensure vibration and noise free operation at high speeds. The blades of the impellers are designed based on highly efficient centrifugal principles. There shall be 2 Re Circulation fans, 1 Extract Fan, 1 Conveyor Motor, 1 Gas Burner, and 1 Gear Motor, etc.
CONTROL INSTRUMENTS: The following control system instruments shall be supplied:

Automatic temperature controller with indicators.
Interlock switch. This switch shall interlock with the flame scanner; in case the circulation fan is not switched to the 'ON' position, the gas supply shall automatically be cut off to the burner.
Gas burner: We shall supply an imported one.
Electrical: Our offer includes all necessary motors, such as a 7.50 HP motor for air circulation, a DOL starter for lower HP motors, and Star Delta starters for 7.50 HP motors. These, along with the temperature controller, will be fitted to the control panel. The incoming supply to the control panel and wiring from starters to individual motors are not included in this quotation.
