Homogenizing device for plant litter

Abstract

The invention discloses a homogenizing device for plant litter. The homogenizing device comprises a sealed chamber, wherein a clear water tank is arranged at the bottom of the sealed chamber; a central main rod and homogenizing cups are arranged in the sealed chamber; multiple balancing poles are connected on the central main rod; a motor and a speed reducer are arranged at an end of each balancing pole; a rotary shaft, a cutting blade, a supporting pipe and a homogenizing cover are arranged below each balancing pole; the central main rod, the balancing poles and the supporting pipes adopt hollow structures, and rubber water pipes are arranged in the central main rod, the balancing rods and the supporting pipes; a washing pump is arranged in the clear water tank. The activity of microorganisms obtaining nutrition from the litter cannot be influenced, the exogenous infection problem of a sample is solved, and the device can be automatically washed after homogenizing.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a homogenizer for plant litter. Background technique [0002] In the field of litter decomposition research, it is often necessary to homogenize plant litter (plant dead tissue) to analyze the activity of saprophytic microorganisms that use litter as nutrition. However, in the field of modern plant research and application technology, there is a lack of special devices for the homogenization of plant tissues. Generally, animal tissue homogenization devices are used for living plants because the tissues are relatively tender. However, due to the lignocellulosic structure of plant litter, the material is relatively hard, and the animal homogenizer will jam when homogenizing it, making it difficult to homogenize it. The temperature will destroy the activity of microorganisms on the litter. In addition, because the animal homogenization device does not take into account the cross-conta...

Problems solved by technology

However, in the field of modern plant research and application technology, there is a lack of special equipment for the homogenization of plant tissues. Generally, animal tissue homogenization equipment is used for living plants because the tissues are relatively soft.

However, due to the lignocellulosic structure of plant litter, the material is relatively hard, and the animal homogenizer will jam when homogenizing it, making it difficult to homogenize it. The temperature will destroy the activity of microorganisms on the litter

In addition, because the animal homogenization device does not take into account the cross-contamination situation, and the isolation device or the replacement of the homogenization chamber is rarely used, which is not suitable for the homogenization of litter

Moreover, for the homogenate with a small amount and a large number of samples, the current homogenate device obviously cannot meet the demand

Therefore, at present, manual grinding is mainly used for processing, but this method is difficult to fully grind plant litter with rich lignofibrous structure, and it is time-consuming and laborious. In the case of weak isolation measures, it is very easy to cause sample damage. Infection with foreign microorganisms, resulting in inaccurate analysis results
