Description

A high-efficiency quantitative and adjustable medium distribution equipment

technical field

The utility model relates to the technical field of machinery and electric equipment, in particular to high-efficiency and quantitative packaging equipment for viscous or easy-to-precipitate liquid culture medium.

Background technique

The traditional method of preparing subpackaged medium to culture containers such as petri dishes, test tubes, and culture bottles is usually to prepare a certain amount of culture medium in a quantitative container, mix it, and pour it into culture containers such as petri dishes. Although such a production method is simple, it would be cumbersome and time-consuming to prepare a large amount of culture medium in factory production. In order to solve the problems of cumbersome and time-consuming media packaging, many media dispensers and packaging equipment have come out one after another.

Imported equipment such as the Swiss B IOTOOL company launched the Petriswiss PS900 (P) automatic flat-panel packaging system. The system has fast dispensing speed, accurate dispensing volume, and many advanced technologies such as plate dispensing, culture medium equalization, plate automatic numbering, plate homogenization, plate automatic dispensing and touch screen. It is currently being widely used in Related fields of research institutions, universities, chemical industry, pharmaceutical industry, hospital, food and microbiology and other industries. Its disadvantages: due to the high degree of intelligence of the system, operators need a high level of education, and people with low education levels cannot operate the system, which is not suitable for ordinary farmers; in addition, the system is only suitable for farmers. It is not suitable for subpackaging of culture containers such as culture bottles, culture cups, culture boxes, and test tubes, and is not suitable for the industrialized production of seedlings.

Agarfill is a simple and practical Italian-made manual media preparation dispenser. This device is suitable for users with small sample volumes. It can be autoclaved as a whole and has a maximum volume of 2.5 liters. The disadvantage of this equipment is: the volume of the container is small, and it is not suitable for the preparation of large batches of medium.

There are various types of domestic sub-packaging systems, which are mainly divided into three categories:

(1) Tube infusion: place the culture container well, and introduce the culture medium into the container by gravity. One person divides the package, pinches the hose head, controls the time of the liquid flow according to experience, and then transfers to the next bottle. The dispensing time of each bottle is more than 2 seconds, and the dispensing volume is uneven;

(2) Drainage from the tap water pipe: Install up to 3 faucets under the mixing bucket, 3 people sit around, each take a basket container, each time take 1-2 bottles, turn on the faucet and put the mixed culture medium into the container, Determine the release amount based on experience, put the container filled with medium into another basket, and then continue to divide the empty container. In a certain period of time, the filling speed of the medium is accelerated due to the increase of the liquid discharge port. But the time of distributing a bottle of culture medium is more than 2 seconds on average, and dispensing quantity is uneven, and input manpower is more.

(3) Quantitative liquid separation: A device similar to the structure of bottled water is used. When the container is used to push the liquid outlet switch, and run once, the liquid is released quantitatively. The equipment is operated by one person and quantitatively distributed. Disadvantages: Only one bottle can be used at a time. After filling one bottle, put it elsewhere, and then take the empty bottle and repack it. The filling time of each bottle is more than 1.5 seconds, which consumes more manpower.

(4) Liquid dispensing by peristaltic pump: The existing liquid dispensing device driven by the peristaltic pump head has disadvantages: only one peristaltic pump head can only be dispensed into one bottle (tube) each time, and the efficiency is low.

(5) Filling machine: It is mostly used in liquor, beverage and other industries, and needs to be equipped with conveyor belts, etc., and the cost is relatively high.

Due to the shortcomings of low efficiency, labor-intensive, inaccurate packaging and other shortcomings of these devices, they are not suitable for industrial seedling production.

Utility model content
