The invention discloses a production technology for soft particle baits and a material pressing device for storing the soft particle baits. The production technology for the soft particle baits comprises the following steps that raw materials are mixed and stirred evenly; water and medicinal liquor are added, and even stir is carried out, so that a sticky bait material is formed; high-temperature sterilization treatment is carried out on the bait material, and the bait material enters a forming device, and is injected into a barrel of the material pressing device; a rotary material pressing assembly of the material pressing device is assembled, after the bait material is cooled to the normal temperature, the bait material is sleeved with a vacuum packaging bag, and vacuum pumping packaging is carried out. The material pressing device for storing the soft particle baits comprises the barrel and the rotary material pressing assembly, wherein one end of the barrel is connected with a taper sleeve, a sealing nut is arranged on the side, far away from the barrel, of one end of the taper sleeve, and the rotary pressing assembly comprises a lead screw, a fixing cover and a sliding block. The production technology for the soft particle baits and the material pressing device for storing the soft particle baits have the advantages that the bait material can be stored for a long time, a fishhook can penetrate through the soft particle baits in place at one step, the soft particle baits immediately pulverize after being thrown into water, and can rapidly lure fishes, the thickness of the soft particle baits can be changed at will, the length of the soft particle baits can be determined at will through pressing, convenience and simpleness are achieved, and recycling storage and repeated use of the baits can be achieved until the soft particle baits are used up.
