Z type Bucket elevator introduction
TAOBO Z-type stainless steel bucket elevator is an enclosed conveying system designed specifically for granular materials. All parts in contact with the product are made of 304 food-grade stainless steel, and the system utilizes a circulating bucket mechanism for scoop-style transport. Its unique Z-shaped configuration enables low-level intake, vertical lifting, and high-level discharge with a directional turn, making it ideal for the automated transfer of fragile granules such as grains, coffee, and nuts. It is frequently integrated with stainless steel hoppers, color sorters, shellers, and dryers to form a complete processing production line.
PRODUCT STRUCTURE
● Vibrating feed hopper: ensures uniform feeding, prevents material accumulation and bridging, and provides stable discharge without clogging.
● Fully enclosed stainless steel housing: a sealed, bent-sheet enclosure featuring a viewing window and a quick-access maintenance door, facilitating the monitoring of internal operations and the removal of residual material.
● Conveying and traction system: Food-grade PP hoppers with chain drive; gentle scooping action significantly reduces seed breakage.
● Variable-frequency drive motor: Supports stepless speed regulation, allows for capacity matching with upstream and downstream equipment, and is equipped with overload and emergency stop safety protections.
● High-level discharge outlet: Supports single or dual-outlet diversion, allowing for direct connection to storage silos, packaging machines, or sorting equipment.
● Mobile base casters: Swivel casters combined with leveling support feet; allows for flexible repositioning within the workshop and is suitable for rotation across multiple production lines.
PRODUCT FEATURES
● Gentle Conveying with Minimal Breakage
● Space-Saving Z-Shaped Configuration
● Food-Grade Hygienic Materials
● Fully Enclosed, Dust-Free, and Eco-Friendly
● Highly Customizable
PRODUCT FUNCTION
● The 304 stainless steel body features a smooth, non-stick surface that is corrosion-resistant and moisture-proof; it can be cleaned simply by rinsing with water. Free from rust contamination, it complies with hygiene standards for grain, oil, and coffee processing.
● The whole machine has a seamless sealing structure, with no material spillage and no dust, which reduces the loss of raw materials, improves the dust environment in the workshop, and meets the environmental protection requirements of food processing.
● Lifting height, discharge position, and conveying capacity can all be customized to requirements; the system supports single-point and multi-point diverted discharge.
TECHNICAL SPECIFICATION

APPLICABLE SCENARIOS
● Coarse grain processing: Transfer and handling within cleaning lines for wheat, corn, mung beans, chickpeas, sesame seeds, etc.
● Coffee processing: Feeding and transferring fresh coffee cherries and dried green beans between hullers, color sorters, and dryers.
● Seed breeding: Sorting and conveying various grain, oilseed, and vegetable seeds while maintaining seed purity.
● Nut snacks: Buffering and transferring granular raw materials such as peanuts, walnuts, and sunflower seeds.

The Z-type stainless steel bucket elevator is a fully enclosed, food-grade conveying system. Its unique Z-shaped layout saves workshop space, while the gentle bucket-tilting mechanism minimizes granule breakage. The stainless steel body is dust-proof and easy to clean. It integrates seamlessly into complete grain or coffee processing lines for vertical material transfer, supports variable frequency speed control and custom height specifications, and is suitable for continuous feeding operations involving various granular raw materials.
Due to the high oil content of sesame seeds, standard carbon steel equipment is prone to rusting and oil accumulation, which can contaminate the product and cause off-odors. The Z-type elevator features food-grade 304 stainless steel for all product-contact surfaces; the smooth finish prevents seeds from sticking and oil from building up, allowing for easy cleaning with a simple water rinse. This design prevents cross-contamination between batches and complies with hygiene standards for the processing of edible agricultural products.
Bucket elevators are widely used and are suitable for soybeans, peanuts, corn, wheat, coffee beans, sunflower seeds, and other sensitive crops that require protection against product damage.

2026 gravity separator utilizes differences in material specific gravity to perform sorting. It is specifically designed to remove impurities and inferior-quality grains that are similar in size to the target seeds—particles that are otherwise difficult to separate using conventional air-screen or vibrating-screen cleaners. It serves as a core piece of precision-sorting equipment in processing lines for grains, sesame seeds, and legumes.

Sesame seeds are extremely small (approximately 1.5–2 mm in diameter) and flat-oval in shape, with a smooth surface, high oil content, and relatively low specific gravity. These physical characteristics present unique challenges for cleaning: while light impurities—such as stalks, husks, dust, and shriveled or empty seeds—can be removed via air classification (aspiration), and oversized or undersized debris can be intercepted through screening, certain contaminants pose a greater difficulty. Specifically, stones, sand, clods of soil, and metal fragments—which are similar in size to sesame seeds but have a significantly higher specific gravity—cannot be effectively separated by either air classification (as they are too heavy to be moved by airflow) or screening (as they pass through or are retained alongside the seeds).

Pakistan is a significant global producer and exporter of sesame seeds, ranking as one of the few oilseed crops for which the country maintains a net export position. According to data from Pakistan’s Ministry of National Food Security and Research, the area under sesame cultivation expanded substantially from approximately 259,900 hectares in the 2022/23 crop year to about 399,800 hectares in 2023/24—an increase of 53%. Production reached approximately 301,200 tonnes, a sharp year-on-year rise of 97.7%. For the 2024/25 crop year, production is projected to climb further to approximately 440,000 tonnes (a 44.7% year-on-year increase), with the harvested area—as recorded by FAOSTAT—exceeding 700,000 hectares. The primary production regions are concentrated in Punjab province (cultivated during the *Kharif* monsoon season, covering approximately 1.76 million acres in 2024) and parts of Sindh province. In recent years, technical cooperation between Pakistan and China, alongside the adoption of contract farming, has led to significant improvements in both crop yields and the level of commercialization.
