Muyang PHY 260 ID Extruder

PHY260ID extruding machine (hereinafter called as extruder) is mainly applicable for expanding raw materials such as corn, rice, grain and rice husk etc. in feed or food processing.

Materials to be expanded enter the feeding bin and are fed into the conditioner by the feeder, and after conditioned by steam in the conditioner, materials enter the extruding chamber. Materials with certain moisture enter the extruder machinery and flow axially through being pushed by the screw. Due to the mechanical friction between the screw and materials, the machine cylinder and materials as well as the friction between material particles, the materials are intensively extruded, stirred and cut, so that they are further pulverized and homogenized.

Since the temperature rises along with the increasing pressure, the properties of materials change under conditions of high temperature, high pressure and high shear force, that is, powdery materials become a pasty mass, starch is gelatinized, protein is modified, fiber is partially degraded and fined, pathogenic bacteria are killed, hygienic indexes are improved and toxic substances are inactivated.

Under the action of great pressure difference, the pasty materials are expanded, dehydrated and cooled as soon as they sprayed out of the die holes. The porous of the cooking extruder expanded product is crisp with loose structure, fine in palatability and flavor.

Installation of Bridge-breaking Feeding Bin and Feeder

One of basic reference data for the control system of the extruder is the material flow rate, and the addition level of water, steam and other liquids in the system shall refer to the material flow rate, therefore the stability of material flow will directly affect that of the whole extruder producing. To ensure stable materials flow, weighing feeding is used in this system, namely, put the whole feeding bin and feeder onto the weighing sensor, so as to form a closed-loop control among weighing sensor, frequency-converted feeder and computer, and then realize feeding.

A basic requirement to the weighing feeding of the feed extruder is a flexible connection between upper and lower interface, namely, the flexible connection between bridge-breaking feeding bin and pneumatic gate at upper part of the bin, as well as the flexible connection between feeder outlet and conditioner inlet, canvas is usually used as the material for flexible connection for this two parts.



Installation of weighing sensor is another important factor affecting the feeding. There are generally two methods for sensor installation: hanging installation and supporting installation, which will be used as required in the site. Necessary measures shall be taken to ensure stability of bin body while hanging installation is used. During production of extruding machine, falling down of materials, when feeding to the feeding bin, will make the whole bin body waggled, the waggling extent and time will closely related to the length of sensor's tie bar. Although the control procedure uses the data prior to feeding for the data in the period of material entering the bin, waggling of the body will be also caused after material enters the bin, the weighing accuracy of sensor will be directly affected, and thus the control procedure will also be influenced, therefore it is required to equip with a limit device at the lower part of bin, and this device shall not affect weighting.



The another method is supporting installation, which will not cause waggling, but the whole bin body on the extruding machinery tends to translocation, therefore sensor should be fixed on a bracket during installation, and it is required to mount limit blocks at both sides of each ear of the feeding bin, so as to prevent the whole bin body from translocation.

It is necessary to pay attention to the position of access door during installation of bridge-breaking feeding bin, and the maintenance platform should be mounted at the lower part of access door while ensuring that the access door can be opened.
