Description

Technical Field

[0001] The utility model relates to the technical field of pickling equipment, in particular to an intelligent low-salt salted duck egg quick pickling device. Background Art

[0002] Salted duck eggs, also known as green skin, are a kind of processed eggs with special flavor and convenient to eat. Salted eggs are a traditional delicacy in my country with a long history. The production methods of salted duck eggs include yellow mud pickling method, brine pickling method and rolling salt pickling method; among them, the brine pickling method currently mostly uses 0.7-0.8m 3 The pickling process is mainly carried out in barrels (some use cement pools instead), and the production method is mainly manual operation. Not only is the process complicated and the pickling cycle long, but it is also easy to cause damage, high salt content, uneven pickling, etc. In addition, due to the special structure of fresh eggs, pickling under natural conditions is a very slow process. Generally, it takes about 40 days to complete the pickling process, and the production efficiency is low.

[0003] Salted egg pickling is a diffusion and osmosis phenomenon formed by saturated brine, egg white and egg yolk. Due to the effect of osmotic pressure, a certain osmotic pressure gradient is formed between saturated brine, egg white and egg yolk. Salt enters the egg white and egg yolk from the brine through the egg pores and multi-layer egg membrane, causing the egg yolk to coagulate and harden, thus achieving the purpose of pickling. Using artificial pickling in a natural environment, after pickling, the salt content in the brine is generally about 23%, the salt content in the egg white is 13%, and the salt content in the egg yolk is 2-3%. Therefore, the product has a high salt content, especially the palatability of the egg white is very poor. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the pickling efficiency is low and the time is long, and at the same time, the salt content in the egg white and the egg yolk differs greatly, resulting in poor palatability.

[0005] To solve the above technical problems, the present utility model provides the following technical solutions: The intelligent low-salt salted duck egg rapid pickling device proposed by the present utility model includes a data control box, a brine mixing tank, a heat exchanger, and a pickling chamber. The brine mixing tank is connected to a water source port and is equipped with an inlet solenoid valve. The brine outlet of the brine mixing tank and the brine inlet of the heat exchanger are connected through a first pipeline. A brine transfer pump is installed on the first pipeline. The brine outlet of the heat exchanger communicates with the brine inlet of the pickling chamber through a second pipeline. The brine outlet of the pickling chamber is connected to the brine mixing tank through a brine recovery pipe. A brine recovery pump is provided on the brine recovery pipe. A third pipeline is connected between the brine recovery pipe and the first pipeline. A computer mainboard is installed in the data control box. The computer mainboard is respectively connected to the internal electrical equipment of the brine mixing tank, the pickling chamber, and the heat exchanger. The computer mainboard is electrically connected to the brine transfer pump and the brine recovery pump. A brine stirrer is further provided in the brine mixing tank. A water level gauge, an upper temperature sensor, and a lower temperature sensor are installed in the pickling chamber to accurately monitor the liquid level height and the upper and lower liquid temperatures in the pickling chamber. The pickling chamber is also provided with a sealed door, an observation window, and a sampling window.

[0006] Preferred technical solution one: It further includes multiple groups of solenoid valves. The solenoid valves are connected to the computer mainboard. A first solenoid valve is installed on the first pipeline. A second solenoid valve is installed on the second pipeline. A third solenoid valve is installed on the third pipeline. A brine recovery solenoid valve is provided on the brine recovery pipe. A fourth solenoid valve is provided at the water outlet of the heat exchanger. A fifth solenoid valve is provided at the water inlet of the heat exchanger. A sixth solenoid valve is provided at the sewage outlet of the brine mixing tank.

[0007] Preferred technical solution two: A brine thermal circulation return pipe is further provided between the pickling chamber and the third pipeline, which is suitable for series return use of multiple groups of pickling chambers to adjust the brine temperature inside the pickling chamber.

[0008] Preferred technical solution three: It further includes a water-cooled air conditioner. The water outlet of the heat exchanger is connected to the water-cooled air conditioner, so that the waste energy can be transferred and utilized, and the energy utilization rate is further improved.

[0009] Preferred technical solution four: The data control box is internally provided with a wireless transmission module, which is connected to an external terminal through a network, and realizes remote control of the device through an APP.

[0010] The intelligent low-salt salted duck egg rapid pickling device proposed by the present utility model has the following beneficial effects when adopting the above structure:

[0011] (1) The present invention is mainly used for the pickling process in the deep processing of salted duck eggs. The wet pickling method is adopted. After fresh duck eggs are cleaned and graded, they are placed in the pickling room by a forklift. The sealing door is closed, and the prepared saturated brine is input into the pickling room through a water pump. After the brine submerges the surface of the upper-layer duck eggs, the brine is heated to 41°C + ±2°C, and the data control box is started to control at 41°C + ±2°C in a circulating heating manner and pickled for 9 - 10 days;

[0012] (2) It has two major functions: heat exchange and dynamic pickling. The heating and the circulating movement of the brine both endow the medium with new energy, greatly improving the penetration and diffusion of salt. Therefore, the pickling time is significantly shortened. At the same time, the osmotic pressure gradient of the tissue structure also decreases, and the salt content of the egg white and yolk tends to be relatively uniform, the salt content decreases, and the palatability of the product is significantly improved.
