Automatic pretreatment device for processing paralytic shellfish toxin samples

Abstract

The invention discloses an automatic pretreatment device for processing paralytic shellfish toxic samples. The device comprises a controller, a motor with a large torque force, a cutter head, a grinding cavity, a first suction connecting pipe, a filter upper cover, a filter paper bag, a filter paper sheet, a filter lower cover, a second suction connecting pipe, a suction filter, and a collecting bottle. The cutter is arranged on the large torque force motor and forms an enclosed space with the grinding cavity. The grinding cavity is connected to the filter upper cover through the first suction connecting pipe. The filter upper cover and the filer lower cover are connected to form an enclosed filter. In the filter, the filter paper bag and the filter paper sheet are arranged in sequence from top to bottom, the filter lower cover is connected to the top end of the second suction connecting pipe in the filter, and the controller is individually connected to the grinding cavity, the filter, and the suction filter though air pipes or liquid pipes. The provided device can automatically process shellfish meat samples before experiments for detecting the paralytic shellfish toxin, the pretreatment operation is simplified, and the pretreatment efficiency is improved.

Description

technical field [0001] The invention relates to sample pretreatment technology, in particular to an automatic pretreatment device for shellfish samples used for detecting paralytic toxins in marine aquatic products. Background technique [0002] Shellfish paralyzing toxins are neurotoxins that are widely present in toxic algae during red tides. In a toxic red tide environment, if shellfish ingest a large amount of toxic algae, a large amount of toxins will accumulate in their bodies. Once people eat this shellfish-related food by mistake, there is a greater risk of poisoning and even death. At present, in the process of shellfish paralytic toxin detection, the pretreatment of shellfish samples can only be done manually. Manual pretreatment requires a lot of equipment, such as rotary evaporator, homogenizer, suction filter funnel, various glass containers, etc., the cost is relatively high, and there are special requirements for the operating environment, generally only in ...

Problems solved by technology

Once people eat this shellfish-related food by mistake, there is a greater risk of poisoning and even death

At present, in the process of shellfish paralytic toxin detection, the pretreatment of shellfish samples can only be done manually

Manual pretreatment requires a lot of equipment, such as rotary evaporator, homogenizer, suction filter funnel, various glass containers, etc., the cost is relatively high, and there are special requirements for the operating environment, generally only in the laboratory

At the same time, the operation process of manual pretreatment is relatively complicated and time-consuming, and it needs long-term training and experienced operators to complete it.

To sum up, manual pretreatment of shellfish samples requires many conditions, the efficiency is low, and it is not suitable for on-site testing.
