The assembling system kind was various in homemade minute, mainly was divided three classes:

(1) flexible pipe transfusion: culture vessel is set, lean on action of gravity that culture is introduced container.One people's packing, hand is pinched the flexible pipe head, rule of thumb controls the time of flow liquid, changes next bottle then over to.Every bottle of branch ETL estimated time of loading divided loading amount inhomogeneous more than 2 seconds;

(2) running water pipe tapping: 3 water cocks are installed at most under agitator; 3 people sit around, and respectively take one basket of container, take the 1-2 bottle at every turn; The leading culture with mixing of fetching boiling water is put in the container; Rule of thumb confirm discharging amount, the container of perfusion cultures base is put into another basket, take empty container to continue packing again.Within a certain period of time owing to tap hole has been accelerated the culture separate-loading packaging.But the time average of one bottle of culture of packing is more than 2 seconds, divides loading amount inhomogeneous, and it is more to drop into manpower.

(3) quantitative liquid separating: adopt a kind of equipment of similar bottled water structure, when leaving the liquid switch with vessel top, and operation once, quantitatively emits liquid.This equipment one man operation, quantitatively packing.Shortcoming: once can only 1 bottle, intact 1 bottle of packing is put into other places, gets the empty bottle packing again, and every bottle of branch ETL estimated time of loading is more than 1.5 seconds, and labor intensive is more.

(4) peristaltic pump separatory: existing peristaltic pump drives the liquid distributing device of Wriggling Pump Head, shortcoming: only limit to 1 Wriggling Pump Head, at every turn can only 1 bottle of packing (pipe), and efficient is lower.

(5) bottle placer: be used for industry such as liquor, beverage more, need be furnished with belt conveyor etc., cost is higher.

Because shortcomings such as poor efficiency, the manpower of these device existence are intensive at present, packing is inaccurate are not suitable for being applied to the production of batch production seedling.
