 **__Brown rice production line equipment__**

 **Raw material (brown rice):**  **Water spray nozzle washing:**  Individual batch of brown rice is washed using a water spray nozzle to inject the pressure of water to remove the unwanted particles (twigs, stalks and stones)
 * The raw material has been stored in cool temperature and less oxygen
 * The raw material is transferred into the silo.
 * The weight of initial load of raw material is 75 kg. In order to produce 10,000 tea bags

 **Weighing conveyor:**  The clean brown rice has been conveyed to the tray and ready to be roasted in the cabinet oven

 **Cabinet oven:** [|Ovens]

 The maximum load of the product is 180 kg. The roasting condition for brown rice is 200 c for 30 min

 **Air blower:**  In order to reduce the time required for cooling process, by using air blower that is different from the laboratory using room temperature to let the product cool. After the roasting of the brown rice, it has been cooled using an air blower to reduce the time of cooling before the material is milled in the hammer mill.

 **Hammer milling:[|h. mill]**  The hammer mill is used to grind the brown rice to specific level then screen the unwanted particle. <span style="color: #000000; display: block; font-family: 'Times New Roman','serif'; font-size: 16px; text-align: left;"> Feed height is low and can be manually feed to the mill.

<span style="color: #000000; display: block; font-family: 'Times New Roman','serif'; font-size: 16px; text-align: left;"> Jet Dust Collector used for dustless environment. <span style="color: #000000; display: block; font-family: 'Times New Roman','serif'; font-size: 16px; text-align: left;"> Capacity range is suitable for up to 200kg/hr.

<span style="color: #000000; font-family: 'Times New Roman','serif'; font-size: 16px;"> The pneumatic system conveys powder for ultimate discharge through rotary air lock valve with dust free operation. <span style="font-family: 'Times New Roman','serif'; font-size: 16px;">However, the grinded brown rice has to be sieved by using sieving machine.

<span style="display: block; font-family: 'Times New Roman','serif'; font-size: 16px; text-align: left;"> **Sieving machine:** <span style="display: block; font-family: 'Times New Roman','serif'; font-size: 16px; text-align: left;"> The brown rice has been sieved with 1mm sieving diameter, after which the material is conveyed to the filling plant.

<span style="display: block; font-family: Arial,Helvetica,sans-serif; font-size: 110%; text-align: left;"> We tried selecting our equipments around the production capacity in an 8 hour shift which Dr Mel had suggested as 10,000 units. We decided that each unit could be a box of 20 sealed tea bags of 2grams each! While selecting the equipments we also looked into options for a continuous process instead of batch. Another roadblock was the storage of raw materials. Each of our raw materials required low temperature and low humidity conditions for storage in order to avoid oxidation and mycotoxins. The storage conditions were also studied and a note was made of the specific technical requirements. = Click to Go back to main page =
