Description

Food heavy metal detection equipment

Technical Field

The utility model relates to a food heavy metal detects technical field, concretely relates to food heavy metal check out test set.

Background

The utility model discloses a utility model with application number CN201921625067.9 discloses a food metal check out test set, the power distribution box comprises a box body, the box downside is equipped with and detects the chamber, heavy metal detector assembly is detecting the chamber upside, the inside crushing chamber that is equipped with of box, box upside threaded connection has and smashes chamber assorted feeding lid, first pivot assembly is furnished with two sets of crushing knife tackle, smash chamber downside fixedly connected with funnel, the funnel bottom is equipped with the screen cloth, it is in first baffle below to detect the chamber, low-speed motor output shaft runs through second baffle fixedly connected with second pivot, second baffle upside is equipped with and detects household utensils, the axle sleeve runs through and detects household utensils bottom and second pivot phase-match, this equipment can smash the back to fixed food, then carry out heavy metal detection.

However, this patent document also has the following drawbacks:

1. the crushed raw materials cannot be accurately weighed, so that the amount of the raw materials on a detection vessel cannot be calibrated; as is well known, the principle of the heavy metal detector for food is as follows: the reflectivity of the reaction product is analyzed quantitatively and qualitatively by photoelectronic technology to lead, cadmium, mercury, arsenic, iron, nickel, aluminum and other elements in the sample, however, the patent document does not set a precise weighing technical structure, and the food entering the crushing cavity is inevitably partially stuck on the side wall of the crushing cavity, a cutter, the side wall of a funnel or a screen in the crushing process, that is, even if the food put in through the feed port is weighed, the weight of the food entering the detection vessel is not ensured to be the same as the original input amount, so that the deviation exists between the food quality actually accepted for detection and the input food quality, and the deviation can not be measured, that is, the food raw material entering the detection vessel can not be calibrated with accurate quality due to the lack of a precise weighing mechanism. If the content of heavy metal in unit mass needs to be detected, the detection result is higher, and the detection result is more deviated from the real result.

2. Smash the chamber and be difficult to wash, detect the food of many different batches and lead to cross contamination easily: as shown in fig. 2 of the patent document, the novel crushing cavity is inevitably adhered to the wall in the process of crushing food raw materials, the crushed raw materials are also remained on the side wall of the funnel and the screen, and the patent document does not design a technical structure which can conveniently clean the crushing cavity, so that cross contamination is easily generated when detecting a plurality of batches of different foods.
