Description

Technical Field

[0001] The utility model belongs to the field of jelly production equipment, and particularly relates to an automatic temperature control and acid adjustment system for jelly production. Background Art

[0002] Background introduction of related technologies: In the field of food processing technology, jelly is a common dessert, and its production process includes steps such as cooking materials, adjusting acidity, and filling. During the acid adjustment process, acidic substances such as citric acid and malic acid are usually added to adjust the pH value and flavor. However, substances such as carrageenan required for jelly gel are damaged by heat under acidic conditions, so it is necessary to precisely control the material temperature during acid adjustment to avoid affecting the quality of jelly. At the same time, in the field of intelligent control technology, temperature adjustment technology is a key link. By intelligently controlling the temperature and acid adjustment equipment, efficient management and control of temperature can be achieved, thereby improving production efficiency and product quality.

[0003] Solutions of the prior art: The existing jelly acid adjustment process is that after the cooking of materials is completed, the material liquid is pumped to a blending tank. After color adjustment and flavor adjustment, acid liquid is added and stirred evenly, and then waiting for filling. At this time, the temperature of the material liquid is below 80°C, and it is necessary to strictly control the temperature of acid adjustment to avoid affecting the quality of jelly.

[0004] Problems of the prior art: Although the existing jelly acid adjustment process can already control the acid adjustment temperature, there are still some problems in actual production. First of all, many manufacturers cannot control the acid adjustment temperature by efficient and reasonable means, and in many cases, the acid adjustment temperature is too high, which will affect the quality of jelly. Secondly, according to the total amount of materials after acid adjustment, the filling time is 30 min - 60 min or even longer. During this period, the colloid will be damaged to a certain extent, resulting in inconsistent jelly quality in the early and late stages of filling. In addition, if the filling equipment fails or production needs to be suspended for other reasons, the materials after acid adjustment may be damaged and wasted. For jelly that needs to add dairy products and protein, more strict control is required, the acid adjustment temperature is lower, and the filling time is shorter. If not controlled well, it will cause the protein to denature into flocs. Finally, since the materials cannot be placed for too long after acid adjustment, the amount of cooked materials in the existing jelly production needs to be set according to the speed of the filling machine, generally 500 kg - 1 t, and the frequency of ingredient cooking and blending is high, consuming manpower and time. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide an automatic temperature control and acid adjustment system for jelly production. This system can accurately control the material temperature during acid adjustment, avoid the influence on jelly quality caused by excessive temperature, and adjust the acid before filling, accurately control the pH value of the material and the time point of adding acid, reduce the waiting time after adding acid to the liquid material being damaged by acid, stabilize the product quality, and avoid inconsistent jelly quality in the early and late stages of filling; by increasing the single boiling amount of the material before adding acid, reducing the boiling frequency, improving production efficiency, reducing the frequency of ingredient boiling and preparation, and saving manpower and time.

[0009] A liquid material return pipe is installed on the pipeline between the outlet liquid thermometer and the second solenoid valve, and the liquid material return pipe is connected to the tubular heat exchanger through a third solenoid valve and the liquid material outlet pipe.

[0010] The mixing and acid adjustment device adopts a twin-screw mixing pump and is connected to a motor for uniformly mixing acid and liquid material.

[0011] The acid supply system includes an acid storage tank, the outlet of the acid storage tank is connected to multiple branch acid liquid pipes through an acid liquid pump and an acid liquid flow valve, and the branch acid liquid pipes are connected to the mixing and acid adjustment device.
