Yuanyin Machinery | Drunken Jiangshan Buffet Restaurant – Jianbo L1-5F Cola Dispenser Implementation Case
I. Client Restaurant Introduction
Zuijiangshan Barbecue, Hot Pot & Seafood Buffet is a popular local buffet restaurant located on the 4th floor of Debai Plaza, Yucheng City, Dezhou, Shandong Province. It focuses on three core buffet categories: barbecue, hot pot and seafood, offering over 200 unlimited dishes at an average per capita cost of about 69 yuan. Positioned as affordable and cost-effective mass catering, it can seat more than 300 diners at the same time, with heavy customer flow during lunch and dinner peaks. The restaurant has extremely high requirements for diverse beverage flavors, cost control, cup-dispensing efficiency and equipment stability, and has pre-reserved water, electricity, countertops, water purifiers and power sockets.
II. Core Pain Points Before Cooperation
Excessively high beverage cost: The restaurant previously mainly used bottled sodas, costing more than 2.5 yuan per cup. The large consumption in buffet scenarios severely squeezed beverage profits, making it impossible to support the cost-effective positioning of "unlimited free drinks".
Limited flavors of bottled drinks: Only 2 options (cola and sprite) were available, failing to meet different customers’ taste preferences, resulting in poor customer experience and hurting the restaurant’s reputation and repurchase rate.
Large storage space occupied by bottled drinks: They took up valuable storage area, and frequent restocking, handling, bottle opening and pouring consumed a lot of labor. Staff were overstretched during peak hours, leading to low operational efficiency.
Limited counter space: The restaurant worried that multi-valve commercial equipment would be too large to fit the reserved countertops, requiring secondary renovation of water, electricity and countertops, which would delay business opening.
No professional maintenance staff on site: Stable technical support and after-sales service were needed to avoid equipment breakdowns disrupting peak-hour business.
III. Yuanyin Solution Selection & Implementation
After communication between the restaurant manager and Yuanyin’s technical team, and considering the wide popularity of cola and high peak-hour dispensing demand in buffets, the customized Yuanyin Jianbo L1-5F 5-valve desktop cola dispenser factory-direct package was selected, perfectly matching the core needs of full-category buffet restaurants.
Customized flavor configuration: Given cola’s broad appeal, a dual cola dispensing valve was specially designed, paired with classic orange and lemon flavors, plus a unique lychee flavor. The 5-valve combination is: Cola ×2 + Lemon + Orange + Lychee, balancing classic staple demands and distinctive experience. Dual cola valves can dispense simultaneously during peak hours without slowing down customer flow.
Equipment package: The package includes a 5-valve cola dispenser, brand-new CO₂ cylinders and multi-flavor syrups, fully equipping all beverage devices required for opening. It supports the restaurant’s business concept of "unlimited variety of drinks" without needing multiple suppliers.
Size compatibility: The equipment is 50cm wide and 68cm deep, perfectly fitting the restaurant’s reserved countertops. It can be placed normally on an 80cm countertop without any water, electricity or secondary renovation, occupying no business space and not disturbing dining circulation.
Water source adaptability: The machine supports dual water sources (tap water / bottled water), matching the restaurant’s existing water and electricity layout. Installation and commissioning are convenient, and the equipment can be put into use on the same day.
IV. Feedback on Implementation Results
Cost control: Based on a 200ml buffet-specific cup, the per-cup beverage cost is as low as 0.28 yuan, an 88% reduction compared with bottled drinks. Sufficient profit margin under the unlimited-refill buffet model greatly cuts the restaurant’s beverage operating costs, fully supporting its cost-effective positioning of "unlimited free drinks".
Rich flavor experience: The customized 5-valve setup uses dual cola valves to meet mainstream demand, lemon and orange as versatile classics, and lychee for differentiated appeal. Customers now enjoy far more beverage choices, the overall dining experience is significantly improved, and the restaurant’s favorable rating has risen noticeably.
Dispensing efficiency: With 5 independent dispensing valves plus dual cola valves, cola can be dispensed through two channels at the same time during peak hours, quadrupling dispensing speed. No more customers queue for drinks, the table turnover rate has increased by 20%, and peak-hour operation runs much smoother.
Equipment fit: The dimensions perfectly match the reserved operating counter; installation and commissioning are quick, with no occupation of business space or disruption to the restaurant’s circulation.
Worry-free supporting services: Complete cylinder support services are provided, so the restaurant does not need to handle gas refilling and transportation on its own. The whole machine is covered by a 1-year warranty with lifetime technical support, bringing no extra burden to daily operation.
V. Customer Testimonial
Original quote from the person in charge of Zuijiangshan Buffet:"Our restaurant focuses on high-cost-performance buffet. Before, bottled drinks were expensive and had few options. After comparing several brands, Yuanyin’s 5-valve cola dispenser solved all our problems perfectly. They even customized dual cola valves for us, which make dispensing extremely fast during peak hours. The five valves cover all customers’ needs. The factory-direct full-payment model has no hidden terms, and the cost dropped to just a few cents per cup. After-sales is also worry-free. Now customers always praise us for having so many drink choices."
