Description

Constant temperature filling device is used in pear syrup production

Technical Field

The utility model relates to transformation of a pear syrup production line, in particular to a constant-temperature filling device for pear syrup production.

Background

Pear syrup is a candy product, and is generally filled in a fluid filling mode. In the filling process, the pear syrup is generally required to be maintained in a relatively constant temperature state, so that the temperature stability of the pear syrup in the filling process is ensured, and the quality and the taste of the product are ensured. If the temperature is too high or too low, the fluidity and viscosity of the pear syrup are affected, resulting in uneven or unsmooth products. Therefore, during the filling process, a constant temperature needs to be controlled to ensure the quality of the product. At present, an electric heating constant temperature mode, a steam temperature control mode or a water bath constant temperature mode is mainly adopted in the filling process.

In the process of filling and temperature controlling pear syrup, electric heating is mainly adopted, and an electric heating rod, an electric heating tube and the like are mainly used for heating so as to achieve the aim of constant temperature; the electric heating has higher energy consumption and higher product heating speed, so that the temperature control fluctuation frequency is overlarge, and the product quality is often unstable because of local overheating or uneven heating phenomenon of an electric heating mode. The fluidity is guaranteed by heating the whole filling container through steam before filling, and because the steam temperature control is mainly carried out on the tank body, heat energy is sometimes lost in the process of outputting pear syrup from the tank body and transporting in a pipeline, so that the fluidity of the product is reduced at the tail end.

Therefore, how to optimize the existing heating mode, so that the pear syrup has better constant temperature in the filling process is worth researching.
