The present disclosure provides a material feeding bag which comprises an inner bag. The inner bag has: an inner bag upper port portion, an inner bag main receiving portion and an inner bag lower port portion. The inner bag upper port portion has an upper port; the inner bag main receiving portion is connected to a lower end of the inner bag upper port portion along an axial direction; the inner bag lower port portion is connected to a lower end of the inner bag main receiving portion along the axial direction and has a lower port for controllable communication with an external hopper entrance. It doe not need to shear the material feeding bag by a scissors when materials is fed, so that it avoids generation of metal debris, and the mating and feeding material operation is fast and simple, and the working environment for an operator is improved.

A silo system includes a storage chamber, an intake pathway associated with the chamber, and a discharge pathway associated with the chamber. The system further includes one or more material sensors associated with the chamber, a plurality of actuators, and a controller that is communicatively coupled to the one or more material sensors and to the one or more actuators. The plurality of actuators enable a deposit of additional material from a transport container into the chamber through the intake pathway at least partially simultaneous with a discharge of material from the chamber through the discharge pathway into an operational silo. The material sensors provide indications of the amount of bulk material in the chamber and the controller is configured to control the one or more actuators in response to sensor data from the one or more material sensors to provide for deposit of material simultaneous with discharge of material.

Provided is a flexible container that can be easily opened. Provided is a flexible container for holding contents that includes an outer bag, an inner bag, a first binding member, and a lid. The outer bag includes a bottom surface portion in which a lower opening is formed. The inner bag is a tubular inner bag that is housed in the outer bag, configured to be filled with contents, and includes a discharge port portion. The discharge port portion forms a discharge path for discharging the contents and extends to a lower side of the bottom surface portion via the lower opening. The first binding member is tied around the discharge port portion to close the discharge path. The lid is attached to an outer side of the bottom surface portion to close the lower opening and cover the discharge port portion. The discharge port portion is narrowed to close the discharge path. The first binding member is tied around the discharge port portion to maintain a state in which the discharge port portion is narrowed. The lid is attached to the outer side of the bottom surface portion to cover the discharge port portion tied off with the first binding member.

A multiple stage pinch valve generally includes a pinch valve body, a manifold top head connected to a proximal end of the pinch valve body and a nozzle head connected to a distal end of the pinch valve body. In one embodiment, the pinch valve body includes a first pinch valve section and a second pinch valve section disposed downstream of the first pinch valve section. In another embodiment, the pinch valve body includes an inner pinch valve section and an outer pinch valve section disposed coaxially around the inner pinch valve section.
