Description

  The present invention relates to a container mixer or the like that stirs powder particles while adding liquid components such as fats and oils. In particular, the present invention relates to a container mixer or the like that can spray liquid so as not to become lumpy and has a relatively simple structure.

  A container mixer is generally composed of a container in which powder particles are accommodated and a mechanism for rotationally driving the container itself. Some containers have a member (such as a stirring blade) that stirs the contents.

  Depending on the type of product, liquid components such as fats and oils and chemicals may be added and mixed with the granular material, or the liquid component may be coated on the granular material. In order to add the liquid component, it is possible to stop the rotation of the container, open the lid of the container, and add the liquid into the container. However, in this case, it is necessary to stop the apparatus, the working efficiency is deteriorated, and the liquid is added to the stationary granular material.

On the other hand, a container mixer has been proposed in which a nozzle for spraying liquid is provided on a lid of a container so that liquid is sprayed when the lid is positioned upward while rotating the container (see Patent Document 1). In this container mixer, a conduit communicating with a nozzle provided on the lid is connected to the tank via a rotary joint. For this reason, since the conduit rotates so as to be swung together with the container or the container rotation shaft, a situation such as twisting or detachment of the conduit may occur.
