Malik engineers is one of the, leaders in development of plastic extruders. , malik engineers offers have recently launched an extruder for producing pre-gelatinised starch from powdered maize with suitable additives and moisture. The extruder is used for cooking the starch powder, which is premixed with moisture to permit partial cooking inside the extruder at appropriate, controlled temperature. Some of the constructional features of this single screw extruder which include:the extruder consists of a specially designed screw and barrel set with venting arrangement to expel hot gasses and extra moisture from the gelatinised starch which also helps to attain higher density of the pgs [pre gelatinised starch] produced from the extruder. The exit end can be fitted with various shapes of desired sections. To permit good hygiene and cleanliness of the product, allall contact parts are manufactured de from stainless steel/hard chrome plated tool steel to permit good hygiene and cleanliness of the product. The main drive consists of suitable high power dc motor with suitable gearbox. Heating is by means of electric resistance heaters, which can be accurately controlled by means of suitable electronic controllers and sensors. For accurate control of process cooking parameters ssuitable controls are provided for accurate control of process cooking parameters. The extruder cooker can be useful to the industry, which produce engaged in production of snack foods and also industry, which produce engaged in production of pharmaceutical grade starch and connected industries. Some general specifications include:the extruder is currently offered in screw sizes of 75 mm and 100 mm with corresponding output capacities of 50 kg and 75 kg per hour approx. Also offered are twin screw extruders with two screws in single barrel for improved results and performance. This single screw extruder finds its applications in:cooking the starch powder, which is premixed with moisture to permit partial cooking inside the extruder at appropriate, controlled temperature.
