Abstract:
1. An apparatus for producing pellets containing entrapped and immobilized microorganisms, comprising: at least one forming frame configured to hold a mixture containing microorganisms, polymerization initiator, and an immobilizing agent solution where the mixture polymerizes into a gel in the forming frame to prepare a block, the forming frame having an interior volume V and a bottom area S; a raw material tank that stores microorganisms; a first chemical tank that stores the immobilizing agent solution; a second chemical tank that stores a polymerization initiator; a stirring and extrusion unit that mixes microorganisms from the raw material tank with immobilizing agent solution from the first chemical tank and polymerization initiator from the second chemical tank to form a mixture, and extrudes the mixture into the forming frame where the mixture polymerizes into a gel to form the block; a transfer stage that transports the at least one forming frame containing the block to a removal device for removing the block from the forming frame; and a cutting unit for receiving the block from the forming frame to cut the block into pellets.
